Question

How many grams of silver could be plated out on a serving tray be electrolysis of solution containing silver in `+1` oxidation 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 the silver plating is `0.00254 cm`? Density of silver is `10.5 g//cm^(3)`.

Answer 1

We Know,
`w_(Ag) = (E.i.t)/(96500) = (107.8 xx 8.46 xx 8 xx 60 xx 60)/(96500)`
`= 272.18 g`
Volume of `Ag = (272.18)/(10.5) = 25.92 mL`
`:.` Surface area `= (25.92)/(0.00254) = 1.02 xx 10^(4) cm^(2)`
