How many grams of silver could be plated...

How many grams of silver could be plated out on a serving tray by the electrolysis of a solution containing silver in `+1` oxidation state of a period of `8.0h` at a current of `8.46A` ? What is the area of the ray, if the thickness of the silver plating is `0.0254 cm` ? The density of silver is 10.5 g cm^(-3)`.

Text Solution

Verified by Experts

Coulumbs passed `=8.46xx8xx60xx60=243648 C`,`=243648/96500=2.52`
Weight of Cu plated `=2.52xx63.5/2g=80.01g ` and volume of Cu plated `=80.01/10.5=7.62 cm ^(3)`
`implies` Area plated out `=7.62/0.00254=3000 cm^(2)`
