In electroplating,the article to be electroplated serves as

Oxidation of species depends upon its oxidation potential. An oxidation reaction is possible for the species whose $E^{o}$ value is lower. Which of the following reactions occurs at the anode during the electrolysis of aqueous $NaCl$?

During the electrolysis of higher concentration of $H_2SO_4$,the product obtained at anode is . . . . . . .

Two statements are given below.
Statement $I$ : Molten $NaCl$ is electrolysed using $Pt$ electrodes. $Cl_2$ is liberated at anode.
Statement $II$ : Aqueous $CuSO_4$ is electrolysed using $Pt$ electrodes. $O_2$ is liberated at cathode.
The correct answer is

The number of electrons delivered at the cathode during electrolysis by a current of $1 \ A$ in $60 \ s$ is (charge on electron $= 1.60 \times 10^{-19} \ C$)

Which of the following reactions occurs at the anode when the electrolysis of an aqueous $CuSO_4$ solution is carried out using copper electrodes?
