How long current of 3A has to be passed ...

How long current of 3A has to be passed through a solution of silver nitrate to coat a metal surface of `80cm^(2)` with a 0.005mm thick layer?
Density of silver is 10.5 `g//cm^(3)`.

Text Solution

Verified by Experts

Volume Of Ag coating `=80 cm^(2)xx0.005/10cm =0.04 cm^(3)`
`implies` mass of Ag coating `=0.4xx1.5g=0.42 g`
`implies` gram equivalents of `Ag=0.42/108=` number of Faraday's `implies0.42/108xx96500C3xximplies t=125s`
