pH stands for "Potential Hydrogen", pH is the most basic and fundamental driving force of all our body function. You may be wondeering what ions are responsible for making a solution an acid or a base. It is simple, Acids produce hydrogen ions H+in a water solution while Bases produce hydroxide ions OH- in a water solution. an example for an acid is HCl and an example for a base is NaOH. The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. one through 6 being acidic, 7 being neutral, and eight through 14 being bases.
The three theories that outline the definition of an acid or a base are The Arrhenius Theory, The Bronsted-Lowry Theory, and The Lewis Theory. There are three different theories are used to define
More hydrogen ions in a solution is a result of lower pH, while fewer hydrogen ions in a solution is a result of increased pH. Meaning that a lower pH level results in a higher enzyme activity reaction and a higher pH level results in a lower enzyme activity reaction (Christianson, 2011 ).
There are many definitions to theory. According to Akers (2009) “theories are tentative answers to the commonly asked questions about events and behavior” (Akers, (2009, p. 1). Theory is a set of interconnect statements that explain how two or more things are related in two casual fashions, based upon a confirmed hypotheses and established multiple times by disconnected groups of researchers.
strong acid or base does not necessarily yield a drastic jump in pH. The acid
In my essay, I am going to talk about acids and bases in the mining business. Acids and bases have many uses in this field, and are actually very important. First, I will talk about hydrochloric acid, and its use in the mining field. Second, I will talk about aqua regia (an acid). Lastly, I will talk about ammonia (a base).
Next, I will proceed to describe what the HOT Theories are, which conditions or requirements contain, as well as mentioning some constraints they may show and that in turn can motivates them.
PH stands for the power of hydrogen. It is also a numeric scale mainly used in chemistry to specify acidity or basicity of a solution. In a solution pH measures the concentration of hydrogen ions. The pH concentration can have many orders of magnitude, meaning it is roughly the negative of the logarithm of base ten of the concentration.
As 10 mL of NaOH was added drop wise, the solution began to have a pink tint. The fuchsia color did not permanently stay until 9mL of NaOH was added. The pH indicator demonstrated when exactly the reaction has neutralized. Because an acid and a base reacted to form water and a salt, the reaction is a neutralization
The simplest experiment for this type of situation would be to use red and blue litmus paper to distinguish between acids, bases and salts. Hydrochloric acid (HCl) makes blue litmus paper change color going from blue to red, making it an acid. Sodium hydroxide (NaOH) makes red litmus paper change color going from red to blue, making it a base. Sodium chloride solution (NaCl) is neutral, since it would only soak blue and red litmus paper, considering that it is a by product of when an acid and a base mix together, neutralizing each other.
strong base ( contained OH ) were 100% ionized in water and they were all
Many have tried to explain what these Theories mean and there has been a lot of Hype about it. Most do not understand what this is all about. So lets make a survey! The very interesting thing is that there are a lot of elements in these Theories which are important for our beliefs and thereby also our Faith!
Chemists have known for some time that the H+ ion doesn’t exist in aqueous solutions as an independent species. The modernized Arrhenius definition of acid is that they are substances that produce H3O+ ions in aqueous solutions. It did not take longer for chemist to find other problems with the Arrhenius definition. In practical terms, the OH- ion is far from being the only base.
A buffer is important to the pH of living system because, the buffer helps keep our body fluids within normal limits. In all living organism the pH of bodily fluids has to stay within normal limits for any organism to maintain life. If a living organism has hydrogen ion concentration level is too high, it will be too acidic or too low on the pH scale. Likewise, if the organism’s hydroxide ion concentration is too high, it will be too basic or too high on the pH scale. If this occurs, it can affect the living organism’s life. An example of this is human blood on the pH scale. The pH level of our blood, when we are healthy is 7.4; which is slightly basic (alkaline). If blood increases on the pH scale it can be life threatening; likewise, if blood decreases on the pH scale below 7.0, it can be life threatening. In order to keep blood at 7.4 it has to have stability that our body has; and a buffer is an essential mechanism to keep blood at a safe level.
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)
An acid is a substance that corrode things and gives things a sour taste to them when comcumed. The word acid comes for the Latin word acidus, which means sour. An acid that can conduct electricity is called an electrolyte. When an acid conducts electricity the electrons are passed through each atom and so on. To test whether a substance is an acid or not, use a litmus paper. The litmus paper can identify acids. During production the litmus paper, that contains wood cellulose, with a chemical that is extracted from some other lichens. If the substance is an acid it will turn the blue litmus paper to red. Also, an acid can be identified by its chemical properties. Acids react with metals to produce salt and hydrogen.
The colour of the acidic solution turned a reddish-pink indicating a low pH whereas the colour of the alkaline solution turned blue-green indicating a high pH, the colour of the solution with an addition of water remained the same, and therefore the hypothesis is supported. The experiment can be improved by using pH strips to get the actual pH value thus allowing the experiment to be more accurate.
