What Are Acids And Alkalis?
Acids and alkalis are opposites. They are both different groups of chemicals. From cleaning products, skincare and food to dangerous car battery, they are everywhere around us. You can tell how dangerous they are from the potential hydrogen (pH) scale (As shown on the left)
The pH scale show how weak or strong an acid and alkali are, 1 being acidic and 14 being alkaline. The 7 in the center stands for neutral (Soren Peder Lauritz Sorensen, 1909).
Acid/Alkali In Houses
Acid and alkali are used a lot in most houses. This includes cleaning, cooking, and washing. Acids and alkalis are also found in every day medicine. There is also acid and alkali in our bodies, which is the one role this essay will talk about.
Acids/Alkalis in Our Body
Acids and alkalis are used to keep human bodies as neutral as possible. The pH of our body is around 7.3 (Felicetti, Marcus Jillian, 2012). A healthy balanced body should have just slightly more alkali than acid. The picture left shows which foods add alkali and acid to our body. The spectrum shows that many fruits and vegetables contain alkali, while foods with a lot of protein in it are acids.
The amount of acid and alkali in our bodies are e¬xtremely important. If the pH of our body changes from anywhere around 7.3, then it could cause some serious damage, like our cells not being able to produce and product properly. Digestion would also be affected. If your body becomes to corrosive or caustic, you would need some serious medical help. If you don’t then it would be very dangerous.
Hydrochloric Acid Inside of Us¬¬¬
There is hydrochloric (HCL) acid made inside of us naturally. They are produced in cells known as “parietal”. HCL is made through many complex reactions...

...eople on earth experience heartburn symptoms daily (Kresser, Chris).
Basically, a something called the lower esophageal sphincter, a muscular valve, keeps all the hydrochloric acid in.
Advantages of Acid in Our Body-Conclusion
Gastric acid kills bacteria and breaks food in our stomach and helps kill bacteria in our stomach. It has totally nothing to do with the acids chosen to swallow. I think that having acid in our body is essential and useful, but eating foods with acids is really bad. Of course, you shouldn’t eat only alkali food because the pH might get to alkaline.
Disadvantages of Acid in our Body-Conclusion
Disadvantages of acids in our body can go on forever. Heartburn, acid reflux, and cancer are just the few. Alkali is shown to be much healthier than acid. I think people should avoid acidic foods as much as possible and stay with alkaline foods.

The sought to determine the effects of mixing various levels of acids and bases to see which combination would have the most explosive reaction, and measure the resulting pH levels. I did this by testing an assortment of different pH levels of acids and bases, mixing them together and measuring the results. Most of the experiments resulted in a pH neutral solution, except for the Sulfuric Acid and the Sodium Hydroxide. By far, the Sulfuric Acid was the most explosive, followed by the Citric and Acetic acid.
Hydrochloric acid is also produced in the stomach, where it. initializes the digestion of proteins. Sodium thiosulphate is a white crystalline salt used as a fixer in photography and as a bleach." Encarta World English Dictionary When hydrochloric acid reacts with sodium thiosulphate, sulphur is. created. The.

There are many people who don't fully understand how the water ionizer works, and they want to find out how alkaline water is produced with this appliance before buying it. Read this article if you are interested in understanding how exactly the water ionizer works, and how it produces alkaline
strong acid or base does not necessarily yield a drastic jump in pH. The acid
Imagine you are eating a sandwich containing wheat bread, ham, lettuce, and Swiss cheese. Do you ever wonder where the nutrients go from all of the previous listed ingredients? Well, when a bite of this sandwich is taken, the mouth produces a saliva enzyme called amylase. This enzyme immediately goes to work by breaking down the carbohydrates that are in the bread. Once, the bite is completely chewed, the contents then are swallowed and go down the esophagus and begin to head towards the upper esophageal sphincter and the is involuntarily pushed towards the stomach. The next passage for the sandwich is to go through the lower esophageal sphincter; which transports the sandwich into the stomach.
Respiratory acidosis happens when the lungs can’t remove enough of the carbon dioxide produced by the body. Excess CO2 causes the pH of blood and other bodily fluids to decrease, making them too acidic. The body is able to balance the ions that control acidity. This balance is measured on a pH scale from 0 to 14. Acidosis occurs when the pH of the blood falls below 7.35. The normal blood pH level is between 7.35 and 7.45. Respiratory acidosis is typically caused by an underlying disease. The lungs take in oxygen and exhale carbon dioxide. Oxygen passes from the lungs into the blood and carbon dioxide passes from the blood into the lungs. Although, sometimes the lungs can’t remove enough CO2. This may be due to a decrease
Chemical: Acids in foods and beverages such as citrus fruits, spices, wines and carbonated beverages; acids produced by acidogenic bacteria following carbohydrate exposure; acids from gastric regulation. (Wilkins, BS, RDH, DMD, 2013)
While the pka for acetic acid can be determined in Graph 1 to be 4.73 the volume of sodium hydroxide in 3mL short of the calculated 13mL point. The published value of 4.76 is similar to the observed pka of acetic acid (Horton et al., 2006). The pka of boric acid was observed to be 9.27 at 14mL of sodium hydroxide added which is consistent with the published value of 9.27 (Silberberg, 2010). Boric acid would be a good buffer for an experiment conducted at a pH of 8.5 because the mixed solution would have a similar concentration of acid and conjugate base. Thereby resisting a change to its pka or 9.27. Acetic acid would have very little resistance to a change in the experiments pH because its pka is 4.76 thus being an already defeated buffer by the time we start the experiment at a pH of
To maintain H+ in the body fluids, the input of hydrogen ions must be balanced by an equal output. On the input side only a small amount of acid capable of dissociating release H+ is taken in with food. Most hydrogen ions in the body fluids are generated internally from metabolic activities. The major source of H+ is through H2CO3 formation metabolically produced CO2. Cellular oxidation of nutrients yields energy with CO2 and H2O as end products. Catalysed by the enzyme carbonic anhydrase, CO2 and H2O from H2CO3 which then partially dissociates to liberate free hydrogen ions and HCO3-. The reaction is reversible because it can go in either direction, depending on the concentration of the substances
An alkali is a soluble base and forms hydroxyl ions (OH-) when placed in water. It can be called a proton acceptor and will accept hydrogen ions to form H2O. An example of an alkali is Sodium Hydroxide (NaOH).

The alkaline earth metals are an interesting group of elements that have many properties and uses in this world. To learn about them will help one learn more about the world around them. These metals are soft, shiny, silvery, and very reactive; although they are not as reactive as the alkali metals, the group of elements right next to them. Speaking of groups, the alkaline earth metals are in the left side and in group 2 of the periodic table. When forming ions, the alkaline metals usually lose 2 electrons to get a positive 2 charge and become more stable. This allows them to take part in ionic bonds, mostly with the halogen family because halogens are negatively charged in their ionic form. Because the alkaline metals are positively charged, they attract and form ionic bonds.
Dental disease, caries are the warning signals for other health complications and development of diabetes, obesity and coronary heart disease. Undernutrition condition associated with high intake of sugar may lead to risk of dental caries. Dental caries affect people physically as well pschycologically and influences how they grow, enjoy their life, look, speak, taste food and socialize themselves. During severe caries they experience pain, discomfort, eating and sleep disturbance, loss of school days and costs of treatment. There is a wealth of evidence that sugars are undoubtedly the most important factors in the development of dental caries. Another factor of dental caries occur because of demineralization of enamel and dentine by organic acids formed by bacteria in dental plague through the anaerobic metabolism of sugar obtained for the diet. Organic acid increased the solubility of hydroxyapatite (main inorganic constituent of tooth enamel and bone) in the dental hard tissues and demineralization occurs. Saliva is supersaturated with calcium and phosphorus at PH 7 promotes remineralization. If the oral PH varies high in for sufficient time then complete remineralization of enamal may occur.If the acid challenge is too high however demineralization dominates then enamel become more porous and a carious lesion will developed.

Ions are critical to human health. As defined by Dictionary.com, an ion is an electrically charged atom or group of atoms formed by the loss or gain of one or more electrons. The human body is the most intricate of ‘designs,’ despite the fact it is composed of basic natural resources called elements. The ions discussed in this paper include oxygen, carbon, potassium, and sulfur. A healthy body is composed of these ions, along with others (zinc, fluoride, iron, etc.). The absence of these elements could lead to an unhealthy body, and make it an easier target for diseases. The chemical formulas, charges, and properties will also be discussed in this document. Also, addressed is the essential role of the ion presented, the way in which the ion serves the body, the diseases that may result from deficiency, and the global distribution of these deficiencies. Ions are an essential part of human health. The ions that are present make the body’s daily functions possible, allowing it to be protected from cruel bacteria or diseases.
