Sulphuric acid is considered to be one of the strongest acids. It was first discovered in the 800A.D by an Islamic chemist by the name of Jābir ibn Hayyān. It is also the world’s most important industrial chemical, often called the “oil of vitrol”. It is a diprotic acid and is very corrosive and it able to eat through many organic substances and the acid is soluble in water at all concentrations. One of the reason as to why sulphuric Acid is important to the chemical industry because it has many different uses examples of this include lead-acid vehicles battery, oil refining and over 50% of sulphuric acid is used as fertilisers.
Physical and chemical Properties
Sulphuric acid contains two hydrogen atoms as well as four oxygen atoms and a single sulphur atom. It is a colourless liquid that is very acidic, with a pH of 0.85, making it very dangerous. Because it is contains the hydrogen atoms it make it an amphiprotic molecule, making it able to both donate and accepts hydrogen atoms, when it needs too. It is also a diprotic acid, with the first stage of ionization,
H2SO4 → H+ + HSO4-
HSO4- → H+ + SO4-2
Some physical properties that sulphuric acid has are:
• Melting Point: 10.3 degrees
• Boiling Point: 338 degrees
• Formula weight: 98.08
• Specific gravity: 1.94
• Flash point: none
• Density: 1.84g/cm3
Sulphuric acid is also a oxidizing agent as well as a drying agent because of its properties with water. The properties it has with water is that it is able to remove the water molecules from any many organic compounds.
Manufacture
Sulphuric acid is produced by dissolving sulphur trioxide (SO3) in water (H2O).
SO3 + H2O → H2SO4
The nitrogen dioxide produced is then used with sulphur dioxide. The two ar...

If sulphuric acid is inhaled or swallowed whole it can cause serious damage to the lungs, mouth and teeth. This can lead to severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns and irritation in the respiratory reactions with burning including pain in the nose and throat.
This is a list of the danger levels of sulphuric acid:
• Health Rating: 4 - Extreme
• Contact Rating: 4 - Extreme
• Flammability Rating: 0
• Reactivity Rating: 2 - Moderate
• Storage Colour Code: White
Sulphuric acid reacts violently with many organic and inorganic chemicals in certain conditions the reaction includes human skins and and with water. It is about to dissolve metals that can lead to reactions releasing hydrogen, which is flammable and can form explosive mixtures that attacks and eats other materials.
Hydrochloric acid is the clear colourless solutions of hydrogen chloride (HCl) in water, hydrochloric acid is also a highly corrosive substance and a strong mineral acid meaning they are formed from inorganic compounds, hydrochloric acid is a monoprotic acid meaning that it can only ionize one H+ ion. As a result hydrochloric acid can be used in a wide range of industrial practices such as removing rust from steel, ore processing, the production of corn syrup and making of PVC plastics. Hydrochloric acid is made using a very straight forward method which involves dissolving hydrogen chloride (HCl) in water, releasing the H+ cation and Cl- anion. In this aqueous form the H+ ion joins water to form a hydronium ion (H3O+)
Most substances fall on a scale ranging from the most acidic to the the most basic with neutral substances falling somewhere in the middle. Scientists call this the pH scale. pH levels are measured in numbers,0 to 14. The closer a substance is to zero the more acidic it would be. The closer to 14 the more basic a substance would be.Now what defines an acid and a base, one might ask? There are three ways of defining acids, each singling out a specific property. The first theory is the Arrhenius Theory with states, that an acid is a substance that produces the ion H+ when in a water solution, while a base is a substance which produces the ion OH- when in a water solution. Examples of an Arrhenius acid are HCl and HNO3. Examples of an Arrhenius base are NaOH and AlOH3.
The MSDS, or material safety data sheet, for 2-butoxyethanol outlines basic health risks that accompany it, along with basic chemical and physical properties. One of the physical properties is the fact that it is a liquid at room temperature, which means it takes the shape of its container and its molecules are not definitively packed. Chemical properties include flammability, which is whether or not it ignites easily, and toxicity, whether or not it is poisonous to humans. 2-butoxyethanol is both flammable and toxic, meaning it does ignite easily and is poisonous to humans It says that 2-butoxyethanol has a health hazard number of two and fire hazard number of two. The health hazard number means that it can cause injury upon exposure and requires rapid medical treatment. The fire hazard number means that it can ignite w...
Phenolic acids are secondary plant metabolites widely distributed in foods, especially fruits and vegetables. In recent years, phenolic acids have attracted a lot of attention because they exist ubiquitously in plants and play protective roles. Phenolic acids possess interesting biological properties, (Beilin, Stocker, & Croft, 1997) that render them interesting to study. They are widespread in crops such as fruits, vegetables, herbs, grains, and seeds and derived foods such as juices, wines, and oils, (Graf, Ameho, Dolnokowski, Milbuty, Chen, & Blumberg, 2006). Phenolic compounds play a key role in thwarting the negative impacts of oxygen and nitrogen reactive species (ROS/RNS), maintaining the redox homeostasis of biological fluids and preventing conditions such as cardiovascular diseases, atherosclerosis, and other degenerative pathologies, such as cancer, diabetes, Alzheimer’s and Parkinson’s diseases, (Shahrzad & Bitsch, 1998).
The physical properties of sulfur are a bright yellow powder. When it is burned you will see a clear blue flame and it has a strong odor. Sulfur has a melting point of 239.38 degrees Fahrenheit, a boiling point of 832.28 degrees Fahrenheit, and the density is 2.67 g/cm. Sulfur has sixteen electrons, protons, and neutrons. When sulfur reacts with the air it produces a gaseous dioxide. It does not react with water under normal circumstances. Sulfur reacts with halogens when it is heated. Sulfur makes up almost 3 percent of the Earth’s mass. At
Acid rain has been proven to have damage forests, fresh waters and soils, killing insect and aquatic life-forms. It also causes damage to buildings and impacts on human health. Many people do not know what acid rain actually is. Acid rain is any form of precipitation that is unusually acidic, low pH levels, higher than normal amounts of sulfuric and nitric acid, occurs naturally and from man made sources. Forms when gases react in the atmosphere with water, oxygen, and other chemicals (what is acid rain?). The only water that will not have some amount of acidity is pure water. Pure water has a pH of 7 which is neutral; regular, unpolluted rain water has a pH of around 5.6. The acidity in rain water comes from the presence of Carbon Dioxide, Nitrogen Oxide, and Sulfur Dioxide. CO2 reacts with water to form carbonic acid. Nitrogen and water react during lightning storms, forming Nitric Oxide. NO is then oxidized to form N02. The NO2 reacts with water to form nitric acid. Due to this, the pH is lowered to be slightly acidic (Acid Rain). Acid rain can occur naturally in the environment, but the problem occurs when human interaction is the cause of the acidic levels.
Ensure gloves are worn at all times when handling strong acids and bases within the experiment of the preparation of benzocaine. 4-aminobenzoic acid (3.0g, 0.022 moles) was suspended into a dry round-bottomed flask (100cm3) followed by methylated sprits (20 cm3). Taking extra care the concentrated sulphuric acid of (3.0 cm3, 0.031 moles) was added. Immediately after the condenser was fitted on, and the components in the flask were swirled gently to mix components. It should be ensured that the reactants of the concentrated sulphuric acid and the 4-aminobenzoic acid were not clustered in the ground glass joint between the condenser itself and the flask. In order to heat the mixture to a boiling point, a heating mantle was used and then further left for gently refluxing for a constituent time of forty minutes. After the duration of the consistent forty minutes the rou...
The effects of inhalant use are many. Almost all the abused products offer effects similar to those of anesthetics, which are slowing down the body functions. Depending upon the dosage, the user may feel a slight stimulation, less inhibition, or lose consciousness altogether. There is also something called Sudden Sniffing Death Syndrome. This means that the user can die after one inhalant use or after many. Immediate effects inhalants offer are nausea, sneezing, coughing, nosebleeds, feeling/looking tired, bad breath, lack of coordination, and loss of appetite. There is considerable damage to ones heart, kidney, brain, liver, bone marrow, and other organs. Mothers who use inhalants during their pregnancy will leave their baby to suffer similar results of Fetal Alcohol Syndrome. There are many long terms effects as well. Permanent brain damage can occur. A person doesn’t even have to be doing it for very long before the brain starts to get clogged. Loss of memory is one of the first signs of brain damage.
Hydrochloric acid is a strong and corrosive acid that is often used as a reagent in laboratories.
The purpose of this project was to discover how the pH level affects corrosion rate. The hypothesis was if the pH level affects the corrosion rate, then the lower the pH level is quicker the corrosion rate would be. This will happen because liquids below the pH level of 7 possess stronger acidic attributes. The effect of pH level on corrosion rate was determined by depositing a copper penny in each of three plastic cups, and then three different liquids by their pH levels, were assigned to be displaced into each cup formulating a chemical reaction to be observed. The results collected during this investigation contradicted with the intended result, this experiment was conducted to determine corrosion rate; Dana Puti Vingear (pH level: 4.5) 4 2/3 days, Tropicana Orange Juice (pH level 3.88) 6 1/3 days, and Sprite (pH level: 3.4) 8 days. The results showed that the hypothesis was refuted. This happened because the preconceived idea was that the liquid with the lowest pH level; Sprite, would have the quickest corrosion rate. Dana Puti Vinegar had the quickest corrosion rate proving the statement wrong, it was discovered that it contains ethanoic acid; acid containing twice the amount of carbon dioxide than a regular acid. To further understand this topic, future research could include; how does the amount of liquid incorporated affect the corrosion rate, how does the temperature of the liquid affect the corrosion rate, and how does the purity of iron affect the corrosion rate?
An acid is a substance that produces hydrogen ions, H+ or hydrodium ionsH3O+ in solution. There are three “kinds of acids”: Arrhenius, BrØnsted-Lowry, and Lewis Acid. An Arrhenius acid is a substance the increases the concentration of hydrogen ion, H+ or hydronium ions H3O+when dissolved in water. You must have water. A BrØnsted-Lowry acid is any substance that donates a hydrogen ion, H+ to another substance. A Lewis acid is any substance that accepts a lone pair of electrons.A strong acid is one that breaks apart close to 100% when in solution (example HCl). When dissolved in water, HCl breaks apart into H+ and Cl- ions. Not all acids break apart. A weak acid is/are chemicals that do not break apart well. Acids have a sour taste, they are: corrosive and electrolytes. Acids react with active metals (group 1 or 2) to produce hydrogen gas, H2 They also react with bases to produce salt and water (a neutralization reaction). An Arrhenius base is any substance that increases the concentration of hydroxide ions (OH-) when dissolved in water. A BrØnsted-Lowry base is one that accepts a hydrogen ion, H+. A Lewis base is any substance that donates a lone pair of electrons. Bases have a bitter taste, bases react with acids to produce a neutralization reaction, and solutions that are basic feel slippery. On the pH scale, 7 is neutral. An acidic solution will have a greater hydrogen ion than hydroxide ion concent...
Flame retardants that contain phosphorus produce phosphoric acid when exposed to the heat of the flame. Phosphoric acid reacts with the burning material to create a thick glassy layer of carbon that protects the rest of the material from thermal degradation, slows the fire down and eventually stops it.
There have been many accounts of chemical warfare and chemical agents all though history. These weapons are very dangerous and have led to many deaths, birth defects, and destruction of the earth. Wepons are one way chemistry is used, and they make up a darker side of chemistry that has an extensive history; but, this is only one way chemistry has played a part in history.
Another system is called the spray dry system. A slurry of alkali is njected into the flue gases. The heat in the flue gases causes water to evaporate. The sulfur dioxide reacts with the drying alkali solution to form a solidi reaction product. There is no waste water from this process.
