Answer to Question #103491 in Physical Chemistry for Hauwa Mohammed rabiu

Question

What is the quantity of electricity needed to deposite 3.25g of silver from silver ion

Answer 1

Molar mass of silver (Ag) is 108

Silver is in mostly +1 oxidation state so equivalent weight is equal to 108

One Faraday (96500 C) charge is required for deposition of one equivalent mass of metal

mole of silver given = $3.25/108$

charge required = $\dfrac{3.25}{108}*96500=1742 C$
