Question

How is a dry cell different from an Electrolytic cell
?

Answer 1

DifferencesElectrolytic Cell (Electrolysis)Chemical Cell / Voltaic CellStructureWith electrical supply.No electrical supply.ElectrodesCan be the same or difference metal (graphite or platinum).Must be two different metals.Flows of electronsFrom anode to cathode through external circuit.From more electropositive metal to less electropositive metal through external circuit.Transformation of energyElectrical energy to chemical energy.Chemical energy to electrical energy.At positive terminalAnode.Oxidation occurs. Anions release electrons at the anode.Cathode.Reduction occurs.

Oxidising agent gain electrons.

At negative terminalCathode.Reduction occurs.

Cations gain electrons from the cathode.

Anode.Oxidation occurs.

Reducing agent releases electrons.
