Electrolysis Quiz

What is an electrolyte?

• A liquid or solution that contains an ionic compound

• A type of wire

• A type of metal electrode

• A type of battery

What is the purpose of the electrodes in electrolysis?

• To attract positive ions

• To attract negative ions

• To transport electrons

• To form a layer of molten lead

What is the positive electrode in electrolysis called?

• Battery

• Electrolyte

• Cathode

What happens at the cathode during electrolysis?

• Bromide ions are oxidized to bromine

• Lead ions are reduced to form pure lead

• Bromide ions are attracted to the positive anode

• Lead ions are discharged to form bromine gas

What is the process of splitting up with electricity called?

• Discharge
