2 mole, equimolar mixture of Na_2C_2O_4 and H_2C_2O_4 required V_1L of 0.1MKHMO_4 in acidic medium for complete oxidation. The same amount of the mixture required V_2L of 0.2M NaOH for neutralization. The ratio of V_1 to V_2 is :

4 mole of a mixture of Mohr's salt and Fe_2(SO_4)_3 requires 500mL of 1 M K_2Cr_2O_7 for complete oxidation in acidic medium. The mole % of the Mohr's salt in the mixture is :

A 3.4g sample of H_(2)O_(2) solution containing x%H_(2)O by mass requires xmL of a KMnO_(4) solution for complete oxidation under acidic conditions. The normality of KMnO_(4) solution is :

A mixture of H_(2)SO_(4) and H_(2)C_(2)O_(4) (oxalic acid ) and some inert impurity weighing 3.185 g was dessolved in water and the solution made up to 1litre. 10 mL of this solution required 3 mL of 0.1 N NaOH for complete neutralization. In another experiment 100 mL of the same solution in hot condition required 4 mL of 0.02 M KMnO_(4) solution for complete reaction. The mass % of H_(2)SO_(4) in the mixture was:
