Analytical chemistry thesis

The target of this project is to construct a general and feasible procedure to determine the acidic equilibrium constants in aqueous solution at 25oC from the data of the potentiometric titration process in a rapid, simple and effective way. Then it will be applied to estimate the equilibrium constants of some new acids.
