What does the pH of a solution mean?
The pH of a given solution refers to the degree of acidity or alkalinity of a solution. pH range is from 0-14. The lower the pH the more acidic and the higher the pH the more basic. Mathematically, pH = -log of concentration of H+ ions in moles per L or pH = -log[H+].
