Electrolysis of Molten Compounds

Front

What happens at the positive electrode during electrolysis?

Back

Negative non-metal ions are attracted to the positive electrode.

Front

What is oxidation in terms of electrons?

Back

Oxidation is the loss of electrons.

Front

Why can ionic compounds not conduct electricity when they are solid?

Back

Their ions are not free to move.

Front

What type of electrical current does electrolysis require?

Back

Direct current.

Front

What is the electrode connected to the positive terminal of a battery called?

Back

Anode.

Front

What is electrolysis?

Back

A chemical process that uses electricity to break down compounds.

Front

What is the role of the cathode in electrolysis?

Back

The cathode is where reduction occurs, attracting positive ions.

Front

What is a molten ionic compound?

Back

An ionic compound that has been melted to allow ions to move freely.

Front

What is the difference between anode and cathode?

Back

Anode is the positive electrode; cathode is the negative electrode.

Front

What ions are attracted to the anode?

Back

Negative ions (anions) are attracted to the anode.
