A salt made of bivalent ions X and Y, each of which is capable of decolourising acidified KMnO4 solution. The salt is likely to be:
Ferrous oxalate
Ferric chloride
Ferrous sulphate
Stannic chloride
As we have learnt,
Ferrous oxalate consists of and
ions. Both act as reducing agents and decolorise acidifed KMnO4 solution. The reactions occur as follows:
Therefore, Option(1) is correct.
