1.	A solution contains mixture of H_(2)SO_(4), H_(2)C_(2)O_420 ml of this solution requires 40 ml of M/10NaOH for neutralization and 20 ml of N/10 KMnO_4 for oxidation. The molarity of H_2C_2O_4, H_2SO_4 are
Answer» ` 0.1, 0.1` `0.1, 0. 05` ` 0.05, 0.1` ` 0.05, 0.05` Solution :Let molarity of `H_(2)SO_(4)= M_1 and H_2C_2O_4=M_2` No. of milli equivalents of `(H_2SO_4+H_2C_2O_4)` = No. of milli EQUIVALENT of NaOH `20(2M_1+2M_2)=40xx1/10` `40(M_1+M_2)=4` `M_1+M_2=0.1 ""...(1)` No.of milli equivalents of `H_(2)C_(2)O_(4)=` No. of mili equivalents `KMnO_4` `20(2M_2)=20 xx1/10` `M_(2) =1/20 =0.05 M...(2)` `M_1 =0.1 -0.05 =0.05M`
