Question

A silver wire is dipped in a solution of copper sulphate in one vessel while in another vessel, a copper wire is dipped in a solution of silver nitrate. What type of reaction take place in the two vessels and why?

Answer 1

When a copper wire is introduced into an aqueous silver nitrate solution, a single replacement reaction occurs. ... This means that it loses electrons and forms copper ions. These ions replace the silver ions that are present in the aqueous silver nitrate solution to form a new compound: copper nitrate

But when silver wire is put nothing happens since silver is less reactive .

Hope it helps
