Question

10 Name the metal which can displace copper form
copper sulphate solution Support your answer
with a word equation
​

Answer 1

any metal which is more active than copper can displace it like k ,Na ,ca

Answer 2

Ans:Zinc(Zn)

Zn + CuSo4 -----------> ZnSo4 + Cu

Zinc+Copper sulphate->Zinc sulphate + copper.

Zinc being a more reactive element (above copper in the reactivity series) than copper displaces copper from its compound. The copper sulphate solution is blue. On addition of the zinc, the solution becomes colourless, and the silver zinc metal is replaced by red/brown copper metal.

Cu + ZnSo4 ---> No reaction

Copper does not react with Zinc sulphate solution, because copper is below zinc in the reactivity series and cannot displace zinc ions from solution.
