What is Meant by pH Measurement?

In Chemistry, the term pH represents the potential of hydrogen. pH is a measurement for acidity or alkalinity. It is a measure of hydrogen ion concentration, which determines the acidity or the alkalinity of the given chemical solution. The value of the pH scale usually ranges from 0 to 14.

For an aqueous solution with a temperature of 25°C with pH value, less than 7 is considered as acidic, whereas pH value greater than 7 is considered as alkaline or base.
Let us consider the chemical acetic acid having a concentration of 5 Molarity. Then the pH value of 5M of acetic acid is equal to 2.03
