Class 12 Chemistry simulations · Electrochemistry

Electrolysis and Faraday’s laws

Pass a current through a solution and calculate the mass of metal deposited at the cathode.

Open the simulation

What to notice

The mass deposited is proportional to the charge passed; for the same charge, metals deposit in the ratio of their M/n.

Key relation

m = M I t / (n F) ; F = 96 485 C mol⁻¹

Try this

Pass 2 A for 30 minutes through CuSO₄. How much copper is deposited?

What you can change

• Metal ion: choose Copper, Silver, Aluminium (from molten Al₂O₃, not aqueous)
• Current: 0.1 to 5 A
• Time: 1 to 120 min

More in Electrochemistry

• Daniell cell and the Nernst equation
• Molar conductivity: strong vs weak electrolytes
