Question

Calculate The Mass Of Copper Deposited By The Electrolysis Of Copper (Ll) Sulphate Solution Placed On Series With A Silver Nitrate Solution, When 0.108G Of Silver Is Being Deposited.

Answer 1

The electrolysis of copper sulphate (CuSO4) solution placed on series with a silver nitrate (AgNO3) solution.

so, equivalents of copper = equivalents of silver

or, mass of copper/equivalent mass of copper = mass of silver/equivalent mass of silver

we know,

• equivalent mass of copper = 63.5/2 = 31.75
• equivalent mass of silver = 108/1 = 108

given, 0.108g of silver is being deposited.

or, mass of copper/31.75 = 0.108/(108)

or, mass of copper = 0.001 × 31.75

= 0.03175g

hence, 0.03175g of copper deposited.
