Question

A silver spoon is kept emerged in an aqueous copper sulphate solution. What change will take place?

Answer 1

when silver spoon is kept in copper sulphate solution as silver is high reactive it takes sulphate ion from the copper sulphate and that copper will be deposited on the silver spoon.

Answer 2

according to the reactivity series ,copper is more reactive then silver. so silver cannot displace copper from its salt solution and hence no reaction will occur in this case
