Question

what do you understand by displacement reactions what will happen when a strip of copper is kept immersed in zinc sulphate solution ​

Answer 1

A displacement reaction takes place when a higher reactive metal reacts with the salt of a reactive metal, it diplaces it from the salt.

•No reaction would occur when a strip of copper us immersed in zinc sulphate solution as copper is less reactive than zinc and so it cannot displace zinc from its salt.
