The use of approximation formulae in calculations of acid-base equilibria-IV Mixtures of acid and base and titration of acid with base.
The pH of mixtures of mono- or diprotic acids and a strong base is calculated by use of approximation formulae and the theoretically exact equations. The regions for useful application of the approximation formulae (error < 0.02 pH) have been identified. The results obtained are used to calculate the curves for titration of mono- or diprotic acids with a strong base.
