Question

a silver spoon is immersed in a aqueous cuso4 solution. what change will take place

Answer 1

When a silver spoon is immersed in a copper sulphate solution, nothing happens. It is because silver is less reactive than copper according to the electrochemical series, so it can not displace copper from copper sulphate solution. However copper would have replaced silver if the case was opposite.
