APPLICABILITY OF NEW ALGORITHMS FOR DETERMINATION OF ACIDS, BASES, SALTS AND THEIR MIXTURES

Regression equations of the Pade type (PADE W, PADE 1/W) and equations with Simms' constants involved (SIMMS 1/W) were applied for the determination of internal parameters (i.e. concentrations, equilibrium constants, activity coefficient of hydrogen ions) related to a titrand-titrant system with one- or two-component sample tested with the species having acid-base properties. The parameters were searched according to an iteration procedure (MINUITS computer program applied).
