Question

6. Which of the following displacement reaction is not possible? a) Fe+CuSO4 → FeSO4 +Cu c) Cu+FeSO4 → CuSo4+Fe b) Zn+CuSO4 → ZnSo4+Cu d) Znt FeSO4 --ZnSO4+Fe​

Answer 1

Answer:

Fe + CuSO4(aq) → FeSO4(aq) + Cu(s) The type of reaction is a displacement reaction.In this reaction , the highly reactive metal iron replaces the Copper in copper sulphate by giving up two electrons and gets oxidized and forms a new compound called ferrous sulphate.

Answer 2

➯Your answer is option d ⌧

• Reaction (i) will take place. This is because Fe (iron) is more reactive than Cu (copper) and so it can displace Cu from its compound (CuSO4 ). On the other hand, copper (Cu) cannot displace iron (Fe), so reaction (ii) will not take place.
