Electrolytic Cell (1)

Chemistry

Not quite remember

I easily remember

Electrolytes

Substances that can conduct electricity in either the molten state or aqueous solution and undergo chemical changes

Non-electrolytes

Substances that cannot conduct electricity in all states

Conductor

Materials that conduct electricity in a solid or molten state but do not undergo chemical changes

Electrolysis

A process whereby compounds in the molten state or an aqueous solution decompose into their constituent elements by passing electricity through them

Factors that affect the electrolysis of an aqueous solution

Standard electrode potential value, Concentration of solution, Type of electrode

Type of reaction at the anode

Oxidation reaction

Type of reaction at the cathode

Reduction reaction

The direction of electrons flow in an electrolytic cell through the connecting wires

Anode to cathode

The applications of electrolysis

The extraction of metals, plating of metals and purification of metals

The position of metal to be electroplated

The cathode
