What is anhydrous ?

1.	What is anhydrous ?
Answer» Salts that have lost their water of crystallization on heating are called ′anhydrous salts′. For example :- When copper sulphate crystals (CuSO4.5H2O), which are blue, are heated strongly, they lose all the water of crystallization and form anhydrous copper sulphate (CuSO4) which is white.
