7.1- OXIDATION AND REDUCTION

Question 1

What is redox short for?

Answer 1

reduction-oxidation

Question 2

Historically, what was oxidation used for?

Answer 2

reactions in which oxygen added

Question 3

What is reduction described as?

Answer 3

reaction in which oxygen removed

Question 4

What happens in terms of electrons when something is oxidised?

Answer 4

loses electrons

Question 5

What happens in terms of electrons when something is reduced?

Answer 5

gains electrons

Question 6

What are redox reactions also called?

Answer 6

electron transfer reaction

Question 7

Why are redox reactions also called electron transfer reactions?

Answer 7

as they always involve movement of electrons

Question 8

How can you see the transfer of electrons in a redox reaction?

Answer 8

separating redox reaction into two half equations that show gain + loss of electrons

Question 9

What are spectator ions?

Answer 9

do not take part in reaction

Question 10

What is oxidation?

Answer 10

loss of electrons

Question 11

What is reduction?

Answer 11

gain of electrons

Question 12

What do reducing agents do?

Answer 12

give away electrons- they’re electron donors

Question 13

What do oxidising agents do?

Answer 13

accept electrons
