Calculate current strength in ampere required to deposit `10 g Zn` in `2` hr. `At. Wt.` of `Zn = 65`.

Text Solution

Verified by Experts

`:' w = (E.i.t)/(96500), :. i = (96500 xx w)/(E.t)`
`[( :'Zn^(2+)+2e rarr Zn),(":. E=(At.wt.)/(2)=(65)/(2))]`
`i = (96500 xx 10 xx 2)/(65 xx 2 xx 60 xx 60) = 4.12` ampere
