Question

Determine the strength in g/L of given CuSO4 solution by titrating with sodium
thiosulphate (hypo) solution acting as intermediate. Normality of known CuSO4 solution
=N/20; Equivalent weight of CuSO4 = 249.678 . volume of known and unknown copper
sulphate used is 25 ml. volume of hypo solution used in titration with known copper
copper sulpahte is 50 ml and volume of hypo solution used in titration with unknown
copper sulphate is 60 ml).​
