WebJun 19, 2024 · The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. WebThe pH scale measures how acidic an object is. Objects that are not very acidic are called basic. The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral—neither acidic or basic.

WebApr 8, 2024 · pH measures the number of hydrogen ions in a solution and it tells us whether a solution is an acid or a base. The pH scale ranges from 0 to 14. Any solution that has a pH from 1 to 6 is acidic, any solution with a pH value of 7 is neutral and any solution with a pH value between 8 to 14 is basic. Following are the applications of pH : WebThe pH scale can be defined as the logarithmic scale, which measures the acidity or alkalinity of the solution depending upon the hydrogen ion concentration. It was introduced by a scientist named SPL Sorenso n in the year 1909. As the proton concentration increases, it will indicate the acidic behaviour of the given solution.

WebThe pH is strictly defined as the negative logarithm of the activity of H X +, and the value of the activity deviates from the value of the concentration, especially at higher concentrations. Just as an example, the standard hydrogen electrode actually uses 1.18 M HCl to ensure that a H X + = 1. – orthocresol May 2, 2016 at 15:57 1
