C) peroxy disulphate
D) dichromate
Correct Answer: C
Solution :
[c] In laboratory, manganese (II) ion salt is oxidised to permagnate ion in aqueous solution by peroxodi-sulphate. \[\underset{peroxodisulphate\text{ }ion}{\mathop{2M{{n}^{2+}}+{{S}_{2}}O_{8}^{2-}+8{{H}_{2}}O\xrightarrow{{}}}}\,\] \[2MnO_{4}^{-}+10SO_{4}^{2-}+16{{H}^{+}}\]You need to login to perform this action.
