The cryoscopic studies of aqueous solutions of compounds such as tartaric acid, sodium hydrogen tartrate, potassium tartrate and potassium citrate were carried out. The freezing temperature lowerings of the aqueous solutions of these compounds were determined. The numerical integration of the Gibbs-Duhem equation was used for the determination of the osmotic and acitivity coefficients in the studied systems.
