Explanation:      Water is a good solvent due to its polarity (it is dipolar in nature) and high dipole moment which can easily dissolve polar compounds. Water dissolves ionic salts by hydrating their component ions. For example, water dissolves NaCl by hydrating and stabilizing the Na+ and Cl– ions.
