- Why it is important to determine the pH value of solution?
pH value play an important role in the control and regulation of chemical and biological processes therefore, it has become indispensable to monitor the pH values.
What is pH value of solution?
The pH value is defined, by the Sorenson Equation
pH = -log10[H+]
10-7 mol/L; pH = 7 (Neutral); H+ ions = OH- ions
at a high concentration, e.g.
1 mol/L = 100; pH = 0 (Acidic)
at a low concentration, e.g.
10-14 mol/L, pH = 14 (Alkaline)
