Question

What happens when zinc rod is dipped in copper sulphate and copper rod is dipped in zinc sulphate solution?

Answer 1

when zinc rod is dipped in copper sulphate solution 
zn displace cu
zn+cuso4---->znso4+cu
when copper rod is dipped in zinc sulphate solution
no reaction takes place
znso4+cu---->no reaction

Answer 2

Answer: when zinc rod is dipped in copper sulphate solution then zinc sulphate + copper will formed.

Znic(zn) + copper sulphate(cuso4) - zinc sulphate(znso4) + copper(cu)

Here zinc will oxidisied as it loose 2 electrons and copper will reduced as it gain 2 electrons.

REdox reaction with evolution of heat.

And wheen cupper rod is dipped in zinc sulphate then no reaction occur because zn is more reactive than copper.
