Question

9.5 Will magnesium react with an aluminium chloride solution? Give reasons for your answer.

9.6 Iron is more reactive than copper, Can you write an activity to prove this?​

Answer 1

Answer:

It forms tetrachloroaluminate (AlCl4−) in the presence of chloride ions. Aluminium chloride reacts with calcium and magnesium hydrides in tetrahydrofuran forming tetrahydroaluminates.

Take some Iron fillings and dip them in the Copper sulphate solution. After some time you will notice that there is a colour change in the solution which is caused due to the displacement of Copper from it solution. This shows that Iron is more reactive than Copper.
