The Concept and importance of pH Scale

May 29, 2018
S.P.L Sorenson, a Danish biochemist in 1909 devised a scale known as pH to represents the H+ ion concentration of an aqueous solution. The pH value of any solution is a number which simply represents the acidity and basicity of that solution. The pH value of any solution is numerically equal to the logarithm of the inverse of the hydrogen ion (H+) concentration. Hence, the pH of solution is referred to as the negative logarithm of hydrogen ion.
