Question

A solution contains cu+2 and c2o4-2 ions which on titration with 1 m kmno4 consumes 10 ml of the oxidizing agent for complete oxidation in acidic medium. The resulting solution is neutralized with na2co3, acidified with dil. Ch3cooh and is treated with excess of ki. The liberated iodine requires 25 ml of 1 m of hypo solution, then that will be the molar ratio of cu+2 to c2o4-2 ions is solution?
