Electrolysis

Cathode

Electrode at which reduction occurs

Anode

Electrode at which oxidation occurs

Electrode

A device for conducting electricity into the liquid

Cation

A positively charged ion

Anion

A negatively charged ion

Electrolyte

An ionic compound able to conduct an electric current

Reason solid ionic substance can't conduct electricity

Ions are in fixed positions

Reason molten/dissolved ionic substances can conduct electricity

Ions are free to move and carry charge

In electrolysis ions go to

Opposite charge electrode

Positive ions go to

Cathode

Negative ions go to

Anode

Discharged

Remove an electric charge by adding/removing electrons

Oxidation in terms of electrons

Loss of electrons

Reduction in terms of electrons

Gain of electrons

When a molten compound is electrolysed the metal forms

at the cathode

When a molten compound is electrolysed the non metal forms

at the anode
