A solution of 0.2 g of a compound containing Cu^(2+) and C_(2)O_(4)^(2-) ions on titration with 0.02M KMnO_(4) in presence of H_(2)SO_(4) consumes 22.6mL oxidant. The resulting solution is neutralized by Na_(2)CO_(3) , acidified with dilute CH_(3)COOH and titrated with excess of KI . The liberated I_(2) required 11.3 mL "of" 0.05M Na_(2)S_(2)O_(3) for complete reduction. Find out mole ratio of Cu^(2+) and C_(2)O_(4)^(2+) in compound.
