Question

Describe an experiment which shows that chlorine is more reactive than iodine. must include an equation in your answer

Answer 1

Answer:

A displacement reaction is basically a reaction where the more reactive element displaces (pushes out) a less reactive element from a compound. For example...

Chlorine is more reactive than iodine (as it is higher up in group 7). Therefore, if you add chlorine water to potassium iodide solution, the chloride will react with the potassium to form potassium chloride (basically, it displaces the iodine). The iodine is displaced from the salt (potassium iodide) and just kind of gets left in the water solution (this turns the solution brown).

Answer 2

• Chlorine is more reactive than iodine as it is higher up in group 7.

Activity

If we add chlorine water to potassium iodide solution, the chloride will react with the potassium to form potassium chloride and it displaces the iodine.
