Question

Silver is electrodeposited on a metallic vessel of surface area
800 cm2 by passing
current of 0 2 A for 3 hours Calculate the thickness of silver
deposited

Pushkar Shukla · Accepted Answer

Given:
Element = Ag = at mass = 107 92
Current = 0 2A
Time= 3h = 10800 secs
In coulombs = 0 2 x 10800 = 2160 C
We know that 1A = 96500 C will deposit 107 92 g of Ag
Therefore total amount of Ag deposited from 2160 C can be found
out as
(107 92/96500) x 2160 = 2 4156 gms
density of Ag =10 47 g/cc
Volume of Ag deposited = Mass / Density = 2 4156 / 10 47
= 0 2307 cc
thickness deposited = Vol / area
= 0 2307/ 800
thickness= 2
