what happens when you place electrodes into copper sulphate and connect it to a power supply ??
what is the pink deposti that forms on the anode ????

There's no need to shout. Nothing deposits at the anode, except oxygen, which bubbles out. Copper will coat the cathode, because the the copper ions (Cu^2+), are reduced to Cu(0), which is just the metal.
The equation is as follows:
Cu^2+ + 2e^- ---> Cu.
At the same time, at the anode,
SO4^2- - 2e^- ---> SO2 + O2

Get to know the Electro negativity table well enough, so that next time you do not confuse with what an Anode is and what a Cathode is.
Anode is the +Ve pole of the electrode and hence will attract the negatively charges ions in the electrolyte.
The Cathode being Vice versa.
