In Figure 30-5, it is observed that the partial molal volume of zinc chloride shows considerable concentration dependence for solutions less than one molar. For one to four molar solutions, the partial molal volume of ZnC^ is about 40ml/mole. For potassium chloride, a more gentle slope is observed, with a value of 32ml/mole around 3 molar. For sodium chloride, a value of 22ml/mole is obtained. Due to the concentration intervals used in calculating the partial molal volumes of these two salts, the volumes for concentrations less than one molar may contain considerable error. PARTIAL TtOLAL VOLUME'S' OF SALTS IN BATTERY ELECTROLYTES Experimentally, densities of solutions of known compositions were determined by weighing. The appropriate calculations were then made to determine the partial molal volumes of zinc chloride in water and in 4 molal potassium chloride, and the partial molal volumes of potassium chloride and sodium chloride in 2.14 molal zinc chloride. This data is presented in Table 30-4.
