Which relations between equivalent weigh...

Which relations between equivalent weight (E) and Molecular weight (M) of reactant are correct for the given change?

A

`FeCl_(2))` into `Fe(OH)_(2),E=(M)/(2)`

B

`Fe_(2)(SO_(4))_(3)` into `Fe^(+2),E=(M)/(2)`

C

`FeSO_(4)` into `Fe_(2)(SO_(4))_(3),E=(M)/(2)`

D

`K_(2)MnO_(4)` into `KMnO_(4),E=(M)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
A, B
`underset("acts as salt")underset(darr)overset(+2)(FeCl_(2))rarroverset(+2)(Fe)(OH)_(2)` Not a redox reaction
EQ wt if `FeCl_(2)=(M)/(2)`
`overset(+3)(Fe_(2))(SO_(4))_(3)rarr""^((+2))Fe^(+2)`
Eq wt of `Fe_(2)(SO_(4))_(3)=(M)/(2)`
