Electrolysis
Electric current splits a compound: cations go to the cathode, anions to the anode.
Open the interactive simulation →How to use this simulation
- Choose an electrolyte (molten NaCl, brine, CuSO₄ …).
- Set the current and press play.
- Read the charge passed and the products at each electrode in the “Faraday” panel.
What to notice
- In water, H₂O may be reduced or oxidised instead of the ions.
- Mass of product ∝ charge passed (Faraday’s laws); 1 F = 96 485 C per mole of electrons.
Try this
Compare molten NaCl and brine. Why do you get different products at the cathode?
