The Ringbom equation for titration of monoprotic acids was derived based on proton condition equation, mass balance equation, titrated fraction as well as the conditional stability constant. The developed Ringbom equation was applied to calculation of pH at any titrated fraction before reaching the stoichiometry point.

Key words: Ringbom equation, Side-reaction coefficient, Conditional stability constant
