How many grams of silver could be plated out on a serving tray by electrolysis of solution containing silver in +1 exidation state for a period of 8.0 hour at a current of 8.46 ampere ? What is the area of the tray if the thickness of silver plating is `0.00254cm` ? Density of silver is `10.5g//cm^(3)`.

Explanation

We, Know,
`w_(Ag)=("E.i.t")/(96500)=(107.8xx8.46xx8xx60xx60)/(96500)=272.18g`
Volume of `Ag=(272.18)/(10.5)=25.92mL`
`E_("cell")^(@)=E_(OP_(Zn//Zn^(2+)))^(@)+E_(RP_(CO^(2+)//CO))^(@)`
`=0.76-0.28`
`E_("cell")^(@)=0.48V`
