Question

Calculate the mass of sliver deposited when a current if 2.2A is passed through a solution salt for 80 minute .(Ag=108g ,1 Faraday = 96500C

Answer 1

Coulombs used = amperes x seconds

C = 2.2 amperes x 80 min x (60 sec/min) = 10,560.
We know that it takes 96,500 C to deposit 108 g Ag metal; therefore,
108 g x (10,560/96,500) = ? g Ag will be deposited with the 10,560 C available.
