In 1909 सोरेन Sørensen, a Danish chemist, introduced the concept of pH as a convenient way of expressing acidity.

pH scale is a commonly used scale to measure the acidity or the basicity of a substance. The possible values on the pH scale range from 0 to 14. Acidic substances have pH values ranging from 1 to 7 (1 being the most acidic point on the pH scale) and alkaline or basic substances have pH values ranging from 7 to 14.
