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.
