The use of approximation formulae in calculations of acid-base equilibria-I Mono- and diprotic acids and bases.
The pH of mono- and diprotic acids 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.
