video Electrochemistry Electrolytic Cells

Electrolytic Cells Electrical energy is supplied to bring about a nonspontaneous redox reaction.

If a voltage greater than 1.10 volts is applied as illustrated to a cell under standard conditions, then the reaction Cu(s) + Zn 2+ (aq) -> Zn(s) + Cu 2+ (aq) will be driven by removing Cu from the copper electrode and plating zinc on the zinc electrode.

Electrolytic processes are very important for the preparation of pure substances like aluminum and chlorine.

Ampere = coulomb / second joules = coulombs x volts I = Q / t Ex - How much silver is plated from AgNO 3 solution by a current of 2.60 A in 1 hour?
