0.10 g of a sample containing CuCO_(3) and some inert impurity was dissolved in dilute sulphuric acid and volume made up to 520 mL. This solution was added into 50mL of 0.04 M KI solution where copper precipitates as Cul and I^(-) is oxidized into I_(3)^(-) . A 10 mL portion of this solution is taken for analysis, filtered and made up free I_(3)^(-) and then treated with excess of acidic permanganate solution. Liberated iodine required 20 mL of 2.5 mM sodium thiosulphate solution to reach the end point. Determine mass percentage of CuCO_(3) in the original sample.

0.80 g of sample of impure potassium dichromate was dissolved in water and made up to 500 mL solution. 25 mL of this solution treated with excess of KI in acidic medium and I_(2) liberated required 24 mL of a sodium thiosulphate solution. 30 mL of this sodium thiosulphate solution required 15 mL of N//20 solution of pure potassium dichromate. What was the percentage of K_(2)Cr_(2)O_(7) in given sample?
