Oxidation and Reduction

Question 1

OIL RIG

Answer 1

Oxidation is loss, reduction is gain (of electrons)

Question 2

what is an oxidising agent?

Answer 2

causes something to be oxidised, it does this by gaining electrons itself - so it gets reduced
an oxidising agent is an electron acceptor

Question 3

what is a reducing agent?

Answer 3

causes something to get reduced, it does this by losing electrons itself - so it gets oxidised
a reducing agent is an electron donor

Question 4

what happens when a more reactive halogen reacts with a less reactive halide?

Answer 4

a more reactive halogen oxidises the ions of a less reactive one

Question 5

what’s the trend for reactivity down group 7?

Answer 5

less reactive, less powerful oxidising agent

Question 6

why do halogens dissolve better in non-polar solvents like liquid hydrocarbons than they do in water?

Answer 6

the halogens are also non-polar molecules

Question 7

what happens when the halogen reaction mixture is shaken with a non-polar solvent?

Answer 7

the halogen is extracted and a deeper colour is given
