2. 25cm3 of the solution made when 1.50g o a copper alloy reacted with conc HNO3 is treated with the excess KI solution. The iodine liberated is titrated against 0.100M sodium thiosulphate. 20.5 cm3 of sodium thiosulpate solution was needed. Calculate the percentage of copper in the alloy. 2S203 2 + 12 -→ S406 2 + 21 2Cu2+ + 41 -→ 2Cul + 12 2. 25cm3 of the solution made when 1.50g o a copper alloy reacted with conc HNO3 is treated with the excess KI solution.
