What is a pH a measure of?

The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution.

Read in-depth answer here. Accordingly, what is pH and how is it measured?

pH is a logarithmic measure of the hydrogen ion concentration of an aqueous solution pH = -log[H+] where log is the base 10 logarithm and [H+] is the hydrogen ion concentration in moles per liter. pH describes how acidic or basic an aqueous solution is, where a pH below 7 is acidic and a pH greater than 7 is basic.

One may also ask, what does pH stand for? potential hydrogen

Additionally, what is the pH scale a measure of?

The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic.

Why do we measure pH?

pH is a measure of how acidic/basic water is. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.
