State one relevant observation for the following :
At the Anode when aqueous copper sulfate solution is electrolyzed using copper electrodes.

Solution

The reaction will be:
$C u S O_{4} \Leftrightarrow C u^{2 +} + S {O_{4}}^{2 -}$
At the anode, oxidation of Copper will take place. The reaction is
$C u \to C u^{2 +} + 2 e^{-}$
Now, the anode will be worn out and will be reduced to a thin uneven strip.
The observation will be anode will be worn out and will be reduced to a thin uneven strip.
