Abstract
The cryoscopical behaviour of the following electrolytes has been investigated: KCl, Li2WO4, WO3‐dissoved in molten K2WO4, BaWO4, Li2WO4, Na2WO4, WO3‐dissolved in molten Na2W2O7; K2CrO4, Na2W2O7, Li2W2O7, M2WO4 (M = Li, Ma, K)‐dissolved in molten K2Cr2O7. The results are interpreted on the basis of TEMKIN'S model of molten electrolytes. Pure molten Na2W2O7 dissoziates into Na+, WO, and WO3. In diluted solutions of alkali ditungstates in molten K2Cr2O7 probably W2O7 probably W2O ions occur. Alkali monotungstates in K2Cr2O7, however, exhibit a complicated behaviour due to chemical reaction with the solvent.
