Salts are electrolytes because they dissolve in water to produce ions. Many general methods are available for the preparation of salts. The method that is chosen for preparing a particular salt depends to a large extent on the solubility of the salt in water.

Rules for Solubility of Salts:

1. All common salts of sodium, potassium, and ammonium are soluble in water.

2. All trioxonitrate (V) salts are soluble in water. e.g AgNO3, Pb(NO3)2, KNO3.

3. All common chlorides are soluble in water except those of lead, mercury, and silver chloride that are insoluble in water i.e PbCl2, Hg2Cl2, and AgCl.

4. All common tetraoxosulphate (VI) salts are soluble in water except PbSO4, BaSO4, CaSO4 which are slightly soluble in water.

5. All trioxosulphate (IV) salts are insoluble in water except Na2SO3, K2SO3 and (NH4)2SO3 which are soluble.

6. All sulphides are insoluble in water except Na2S, K2S and (NH4)2S that are soluble.

7. All acid salts are soluble in water.

8. All trioxocarbonate (IV) salts are insoluble in water, except those of sodium, potassium and ammonium that are soluble in water.
