3.0g of a sample of impure crystalline copper sulphate was dissolved in water and made up 250 ml. solution 20.0 mL of this solution required iodometrically 23ml. of sodium thiosulphate 24 ml of this sodium thiosulphate solution required 25 ml. of a N/25 solutionof a pure crystalline copper sulphate. Find out the percentage purity of the impure sample of crystalline copper sulphate (Eq. Wt of CuSO. SH₂O=249.71). Give necessary equations.

Why only ferrous sulphate is not used to make a primary standard solution instead of ferrous ammonium sulphate, Mohr's salt?
