A water sample contains the following impurities per litre
Ca(HCO3)2= 81 mg Mg(HCO3)2=73 mg, CaSo4=68,MgSo4=60mg KCl= 100mg.
Calculate the quantity of lime and soda required in kg for softening 50000 litres of water if the purity of lime and soda are 80% and 90% repectively
at wt. Mg=24, S=32, C=12, N=14, O=16, Cl=35.5, Ca=40
