Given: The amount of MgSO4 = 100 mgs/lit The amount of hardness producing salt

Amount equivalent to CaCO3 = ---------------------------------------------------------- X 100

Molecular weight of hardness producing saltWe know that, the molecular weight of MgSO4 = 120

Amount equivalent to CaCO3 =100 x 100/120 = 83.3 mgs/lit

2. A water sample contains 200 mgs of CaSO4 and 75 mgs of Mg (HCO3)2 per litre. What is the total hardness interms of CaCO3 equivalent? Solution:Name of the hardness

Temporary Hardness = Mg (HCO3)2 = 51.4 mgs/litPermanent hardness = CaSO4 =147 mgs/lit.Total hardness = Mg (HCO3)2 + CaSO4

= 51.4 + 147= 198.4mgs/lit

3. Calculate the carbonate and non-carbonate hardness of a sample water containing the dissolved salts as given below in mgs/lit Mg(HCO3)2 = 10;Ca(HCO3)2 = 40; MgCl2 = 21.; and NaCl = 20Solution

NaCl 20 NaCl does not contribute any hardness to water, hence it is ignored.
