Displacement Reactions Between Halogens And Halide Ions

Question 1

The more reactive halogens (ie the strongest oxidising agents) will displace what

Answer 1

the more reactive halides (ie the strongest reducing agents) from solutions of their ions

Question 2

Cl2(g) + 2Br- (aq) -> 2Cl- (aq) + Br2(aq)
Observations

Answer 2

Chlorine displace bromine from solution
Organic ➡️ clear, colourless to orange

Aqueous ➡️ clear, colourless to orange

Question 3

Cl2 (aq) + 2l- (aq) -> 2Cl- (aq) + l2 (aq)
Observations

Answer 3

Chlorine displace iodide ions from solution

Organic ➡️ clear, colourless to purple

Aqueous ➡️ clear, colourless to brown

Question 4

Br2 (aq) + 2l- (aq) -> 2Br- (aq) + l2 (aq)

Observations

Answer 4

Bromine will displace iodide ions from solution but not chloride ions

Organic ➡️ clear, colourless to purple

Aqueous ➡️ clear, colourless to brown

Question 5

What can iodide displace

Answer 5

Cannot displace bromine or chloride ions from solution
