General Properties of Salts:
Salts are the white crystalline powder formed due to neutralization reaction of an acid and a base. Salts show following general properties:
1. Melting and boiling points:
Salts are mostly solid which melt as well as boil at high temperature.
2. Water of crystallization:
Salts are found as crystals with water molecules present in them. This water is called water of crystallization and such salts are called hydrated salts. E.g.: copper sulphate . On heating, hydrated salts lose their water of crystallization, crystals lose their shape, color and change to a powdery substance. The hydrated salt that have lost their water of crystallization are called anhydrous salts.
3. Hydrated and Anhydrous Salts:
The crystals of some salts have a fixed number of water molecules (called water of crystallization) loosely associated with them such salts are called hydrated salts. These hydrated salts on heating lose their water of crystallisation and change to powdery substance called anhydrous salt.
4. Reaction with an Acid:
When a salt reacts with an acid, another salt and acid are formed. For example, when sodium chloride is heated with sulphuric acid, sodium hydrogen sulphate (at low temperature) and then sodium sulphate (at high temperature) are produced and hydrogen chloride gas is evolved.
