Problems based on Hardness1. A sample of water contains 100 mgs of MgSO4 per litre. Calculate the hardness in terms of CaCO3 equivalents.Solution
(10) 5
Page 40 of 52
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
producing saltsAmount in
mgs/litMolecular
weightAmount equivalent
to CaCO3
CaSO4 200 136 200 X 100 / 136 = 147 mgs/lit
Mg(HCO3)2 75 146 75 x 100 / 146 = 51.4 mgs/lit
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

required 10.0 ml of the acid to phenolphthalein end-point and 14.0 ml of the acid to methyl orange end-point. Determine the type and extent of alkalinity present in the water sample.
Solution:Strength of HCl = 0.02 Nphenolphthalein end-point = P = 10.0 mlmethyl orange end-point = M = 14.0 ml
Since P > M,
the water sample must contain only OH- and CO32- alkalinities and there
cannot be any HCO3- alkalinity.
