The solid dissolves readily in water and its solution s have a salt -like taste. It dissolves in water does not conduct electricity when solid but does when melted and it has a high melting point 804 C. Potassium Chloride Kcl Properties Uses Side Effects Conpounds with ionic bonds have high melting points. . Why does strontium chloride have a high melting point. Aluminum chloride molecules are attracted to each other by van der Waals forces. The molar mass of KCl is 745513 gramsmol. Why does potassium chloride have a high melting point. Since more energy is required to break the bonds the melting point of calcium will be higher than that of potassium. All ionic compounds have high melting points for this reason. Since more energy is required to break the bonds the melting point of calcium will be higher than that of potassium. This is because sodium chloride is an ionic compound and aluminum chloride is a ...
