Find the thickness of the electro silver...

Find the thickness of the electro silver if the surface area over which deposition occurred was `100 cm^(2)` and a current of `0.2A` flowed for `1 hr` with the cathode efficiency of `80%` . Density of `Ag=10 g//c c (Ag=108)`.

A

`6.4xx10^(-5)cm`

B

`6.4xx10^(-4)cm`

C

`6.4xx10^(-7)cm`

D

`6.4xx10^(-8)cm`

Text Solution

Verified by Experts

The correct Answer is:
2
`thxx"Area"xx"density"=(108xx0.2xx0.8xx3600)/(96500),th=(108xx0.2xx0.8xx3600)/(96500xx100xx10)cm=6.4xx10^(-4)cm`
