1.	(a) What happens when MgSO_4 .7H_2 O is heated? Write the appropriate equation. (b) Define solubility.
Answer» Solution : (a)` MgSO_4 . 7H_2 O `has water of crystallization is 7. When magnesium SULPHATE heptahydrate crystals are gently heated, it loses seven water molecules and becomes anhydrous magnesium sulphate. ` UNDERSET("magnesiumsulphateheptahydrate")( Mg SO_4 .7H_2 O) underset("cooling")overset("Heating")hArrunderset("anhydrousmagnesiumsulphate ") ( MgSO_4+ 7H_2 O)` (B) SOLUBILITY: It is DEFINED as the number of grams of a SOLUTE that can be dissolved in 100 g of a solvent to form its saturated solution at a given temperature and pressure.
