How many grams of silver could be plated out on a serving tray by electrolysis of solution containing silver in +1 oxidation state for a period of 8 hours at a current of 8.46 ampers. What is the area of the tray if the thickness of the silver plating is 0.00254 cm? Density of silver is 10.5 gcm3.

Options:

Answer:
A
Solution:

W=ECtF

=107.8×8.46×8×60×6096500=272.178 g

Volume of silver=wt.Density

=272.17810.5=25.9 ml

Surface area=VolumeThickness

=25.950.00254

=1.02×104cm2
