1. A water sample having following data:
CaSO4 124 mg/lit, CaCl2 = 90 mg/lit, Ca(NO3)2 = 29.6 mg/lit, NaCl= 50 mg/lit. Calculate temporary, permanent and total hardness of water sample?
Numerical on EDTA method
Q 2. 5 gm of CaCO3 was dissolved in 1 lit water solution and 100 ml of this solution required 18 ml of EDTA solution for titration. 100 ml of sample hard water required 16 ml of EDTA solution for titration. On boiling, this water required 14 ml of EDTA solution. Calculate Total, permanent and Temporary hardness of water?
