1.7 Oxidation, Reduction And Redox Reactions

Question 1

What are REDOX reactions ?

Answer 1

• REDOX reactions are electron transfer reactions, they require the movement of electrons
• They occur when oxidation and reduction are happening simultaneously
• Redox reactions involve a transfer of electrons from the reducing agent to the oxidising agent

Question 2

Define Oxidation

Answer 2

This is the process of electron loss, increase in oxidation number, gain of oxygen

Question 3

Define Reduction

Answer 3

This is the process of electron gain, decrease in oxidation number, loss of oxygen

Question 4

What is an Oxidising Agent ?

Answer 4

An oxidising agent is one that accepts the electrons. It causes the oxidation and gets reduced

Question 5

What is a Reducing Agent ?

Answer 5

A reducing agent is the one that donates the electrons. It causes the reduction and gets oxidised

Question 6

State, in terms of electrons, the meaning of the term oxidising agent (1)

Answer 6

Electron acceptor

Not electron pair
