Question

Zinc displaces cooper from its aqueous solution whereas the reverse reaction is not possible why

Answer 1

Bonjour!

Zinc is highly reactive than copper in reactivity series so Zinc can displace copper from copper sulphate solution but copper cannot displace zinc from zinc sulphate solution.

Answer 2

Answer: This is so because zinc is more reactive than copper.

Explanation:

The displacement of one metal from its aqueous solution by another metal is known as single displacement reaction.

The reactivity of metal is given by the reactivity series. The metal which lies above in the reactivity series is more reactive than the metal which lies low in the reactivity series.

Zinc lies above in the reactivity series than copper. Thus, it will easily displace copper from its aqueous solution.

The reaction for this follows the equation:

$Zn(s)+Cu^{2+}(aq.)\rightarrow Zn^{2+}(aq.)+Cu(s)$
