How would you show that silver is chemically less reactive than copper?

Answer»

Solution :By displacement REACTIVE silver can be SHOWN to be chemically less reactive than copper or copper is more reactive than silver. If a piece of silver is immersed in a solution of copper sulphate. No reactive will TAKE place because silver is less reactive than copper and will not DISPLACE copper from the copper sulphate solution.
`CuSO_4(aq)+Ag(s) to No reaction`
On the other HAND if a copper plate in a solution of silver nitrate, copper will slowly displace silver from the solution and blue solution of copper nitrate is formed.
`2AgNO_3(aq)_(Colourl ess)+Cu(s)toCu(NO_3)2_(Blue)+2Ag(s)`
This shows that copper is more reactive than silver.
