Study of Ph
pH is the measure of H+ (a proton) a concentration of a solution. In order to understand pH, a scale has been designed, this scale ranges from 0 to 14. Anything from 0 to 6.99 is acidic, a substance that increases hydrogen ions concentration in a solution, such as lemon juice. If the scale ranges from 8 to 14 would be determined as a basic solution, a substance that reduces the hydrogen ions concentration in a solution, an example of this would be ammonia. If the solution concentrate has a pH of 7 this would be neutral, such as pure water. Although pH can be determined in various ways, the most common ways to indicate pH are by using indicator papers. One type of paper is called litmus paper, this paper merely tells you whether it is acidic or basic, it does not establish what the pH may b
pH paper, which is another type you may use, can actually approximate the actual pH of a solution. Before starting my experiment I recorded my test substances I would be using, I tore of a small piece of blue litmus paper and dipped into my solution number one a recorded the color. General Biology Lab Manual 3rd edition, Kendall/Hunt Publishing Company, Iowa. Coke and Aspirin were determined to be acidic and ammonia and antacid turned out to be basic solutions. The red paper, which determines the pH more approximately also, determined the same results. I repeated this step and recorded the colors as I went along to each different solution. The experiments coincided with each other, the blue litmus paper said antacid and ammonia are basic and the remaining solutions lemon juice, coke and aspirin were acidic. For example, as stated in, Biology the 4th edition book (p. I then preformed the same experiment with my red litmus paper.
