Electrolysis:

Question 1

What are electrolytes?

Answer 1

• When an ionic compound is melted or dissolved in water, the forces of attraction are broken and the ions are free to move.
• Liquids and solutions can now conduct electricity.
• Electrolytes.

Question 2

What are electrodes?

Answer 2

• In electrolysis there are 2 electrodes, made from conducting materials e.g Graphite or metal.
• Negative electrode: Cathode, covered with electrons.
• Positive electrode: Anode, lack of electrons.

Question 3

What happens during electrolysis?

Answer 3

• Negative Ions are attracted to the Anode and are discharged so become nuetral.
• Positive Ions are attached to the Cathode where they are discharged.

Question 4

What happens to the positive ions?

Answer 4

• Reduced.

- Gain electrons to to form an atom.

Question 5

What happens at the negative ion?

Answer 5

• Loose electrons to form an atom.

- Oxidisation.
