Decolourisationof acidified permaganate in fast by Mohr'ssalt , butis solw by oxalate . Expalin . |

Answer» Solution :Oxalate, `""^(-)OOC-COO^(-)`, on OXIDATION GIVES `CO_(2)`. It is involves breaking of C-C bond, which requires energy. Hence decolourisation of `MnO_(4)^(-)` by `C_(2)O_(4)^(2-)` is slow. On the other hard Mohr.s SALT is a COMPLEX salt containing `FE^(2+)`ions . |
