however will there be any discolouration on the anode or in the solution.
All Help appreciated.
Anode is made up of IRON and will get oxidized as iron ion and replaces Cu2+
from the solution.So there is discoloration of the solution color from blue to pale yellow ,size of anode decreases and size of the cathode will increase. Cu2+
will come out of solution as Cu after gaining two electrons from cathode and will deposit on the cathode.
