1.	How would you calculate the equivalent mass of anhydrous oxalic acid and hydrated oxalic acid.
Answer» Solution :In ACID medium, 16 g of oxygen is used for oxidation of 90 g of oxalic acid. `:.` 8 g of oxygen will oxidize = `90/16 xx 8 = 45 g eq^(-1)` EQUIVALENT MASS of Anhydrous oxalic acid = 45 g `eq^(-1)` Equivalent mass of `underset(COOH)(COOH)xx2H_(2)O = ("Molar mass")/("Basicity")` = `126/2` = 63 g `eq^(-1)`
