1.	What is the equivalent weight of oxalate ion C_(2)O_(4)^(-2) as reducant?
Answer» SOLUTION :`Cr_(2)O_(4)^(-2) to 2CO_(2)+2E^(-)` Equivalent weight of `C_(2)O_(4)^(-2)ion`= `=("Formula weight of "C_(2)O_(4)^(-2))/("No. of electrons involved in the reaction")=(88)/(2)=44` Equivalent weight of `Na_(2)C_(2)O_(4).2H_(2)O=("Mol.Wt. of"Na_(2)C_(2)O_(4).2H_(2)O)/(2)=(175)/(2)=85`
