A solution of `Ni(NO_(3))_(2)` is electrolyzed between platium electrodes using a current of `5A` for `20 mi n`. What mass of `Ni` is deposited at the cathode ?

Text Solution

Verified by Experts

Eq. of Ni deposited
`w/E=(i.t)/96500=(5xx20xx60)/96500=0.0622`
or `"w"_(Ni)` = `0.0622xx58.71//2`=1.825 G
`(Ni^(2+)+2erarrNi)`
