6.4 Soluble and insoluble salts
Soluble salts are salts that dissolve in water at room temperature, and insoluble salts are salts that do not dissolve in water at room temperature.
General rules for the solubility of salts help predict the solubility of various ionic compounds in water. These rules are necessary to understand the reactions of aqueous solutions. Here is a detailed description of the solubility rules:
