1.	Explain why does coloure of `KMnO_(4)` disppear when oxalic acid is added to its solution in acidic medium.
Answer» `KMnO_(4)` oxidizes oxalic acid to `CO_(2)`and half is reduced to `Mn^(2+)` which is colourless. `underset("(Coloured)")(2MnO_(4)^(-)) + 16H^(+) + 5C_(2) O_(4)^(2-) rarr underset("(Colourless)")(2Mn^(2+))+ 8 H_(2)O + 10 CO_(2)`
