Question 1

What happens during neutralisation?

Answer 1

• Water is produces

- Acid and base is present in reactant’s side

Question 2

Oxidation properties

Answer 2

• Diatomic molecules individually oxidation number is always zero
• Metals individually oxidation number is zero
• Oxygen’s oxidation number is always -2
• Cofficients are not counted (the front number)

Question 3

Oxidation

Answer 3

1) Oxygen is added to an element or a compound
2) An element, ion or compound loses electrons
3) The oxidation state of an element is increased
- Oxidation is loss of electron

Question 4

Reduction

Answer 4

1) Oxygen is removed from an element or a compound
2) An element, ion or compound gains electrons
3) The oxidation state of an element is decreased
- Gain of electron

Question 5

Agents

Answer 5

• The species that has undergone oxidation is called reducing agent
• The species that has undergone reduction is called oxidation agent
