Equal quantities of electricity are passed through three voltameters containing `FeSO_4` , `Fe_2 (SO_4)_3` and `Fe_2(SO_3)_3` . Consider the following statements :
1. The amount of iron deposited in `FeSO_4` and `Fe_2(SO_4)` are equal.
2. The amount of iron deposited in `Fe(NO_3)_3` is two third of the amount of iron deposited in `FeSO_4`
3 The amount of iron deposited in `Fe_2(SO_4)_3` and `Fe(NO_3)_3` is equal
The correct statements is/are

Options

A. 1 only
B. 1 and 2 only
C. 2 and 3 only
D. 3 only

Answer

C

Explanation

`Fe^(2+)+2e^(-)toFe,Fe^(3+)+3e^(-)toFe` Weights deposited are in the ratio of their eq. wts. Hence, (2) and (3) are correct.
