The same electric current is passed through solutions of ferrous sulphates , FeSO_(4) and silver nitrate, AgNO_(3) . If the amount of iron deposited is (Ag=108, Fe=56, N=14, S=32, O=16)

Answer»

14 g
2.7 g
0.7 g
1.35 g

Solution :`(W_(FE))/(W_(AG))=(E_(Fe))/(E_(Ag))`
`THEREFORE W_(Fe)=(28xx2.7)/(108)=0.7 g`
