When one faraday current is passed which of the followingwoulddeposit1 gatomicweight of the metal

Answer»

NaCI
`BaCI_(2)`
`AICI_(3)`
`CuSO_(4)`

Solution :1 G ATOMIC WEIGHTOF metal will be deposited by one faraday of currentwhen metalhas one unitpositivecharge
a `NacI or Na^()CI^(-)`
b `BaCI_(2) or Ba^(2+) 2CI^(-)`
c `AICI_(3) or AI^(3+) 3cI^(-)`
d `CuSO_(4) or Cu^(2+) SO_(4)^(2-)`
`therefore`1 g atomic weightof `Na^(+)`is deposited by 1 F of CURRENT
