Question

molecular weight of molars salt is 392 its equivalent weight when it is oxidised by kmno4in acidic medium is​

Answer 1

Answer:

Explanation:

the reaction of mohrs salt and kmno4 gives

2kmno4+10feso4.[NH4]2So4.6h2o+8h2so4 gives k2

so4+2mnso4+10[nh4]2so4+2Fe2so43+8h2o

oxidation of mn changes from +7 to +2

oxidtion state of fe changes from +2 to+3

equivalent weight =392/1

                               =392
