Question

During electrolysis, the gram equivalent of silver metal from ${Ag}^{+}$ ions deposited by passing $48250$ coulombs of electricity is:

• A. one-half
• B. one
• C. one-third
• D. two

Answer 1

The correct option is A one-half

$Ag\rightleftharpoons A{g}^{+}+e$

1 gram equivalent of silver metal from Ag(I) ions require 1 faraday of electricity.

1 faraday of electricity is 96500 coulombs.

96500 coulombs will deposit 1 g.equivalent of silver.

48250 coulombs will deposit 0.5 g.equivalent of silver.
