Electrolysis

Question 1

What happens when an ionic compound is melted or dissolved in water?

Answer 1

• Forces of attractions are broken and ions are able to move.
• Liquids and solutions can conduct electricity.
• These liquids or solutions are called:
• Electrolytes.

Question 2

Structure of electrolysis?

Answer 2

• 2 electrodes (made of a conducting material).
• Negative electrode= Cathode (covered in electrons).
• Positive electrode = Anode (Lack of electrons).
• Positive ions are attracted to the Cathode.
• Negative ions are attracted to the Anode.

Question 3

What happens to the positive ions?

Answer 3

• gain electrons to form an atom.

- (reduction).

Question 4

What happens to the negative ions?

Answer 4

• Loose electrons to form the atom.

- Oxidation.
