General Properties of Salts

Properties of Salts:

  • Melting and boiling points: salts are mostly solid which melt as well as boil at high temperature.
  • Solubility in water: salts are soluble in water. Eg: sodium chloride, potassium sulphate, lead chloride, copper carbonate etc are soluble in water.
  • 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 CuSO_4.5H_2O.  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.
