Which of the following elements is obtained by the electrolysis of the aqueous solution of its compound?

During the electrolysis of aqueous $NaCl$ using platinum electrodes,which product is formed at the cathode?

The platinum electrodes were immersed in a solution of cupric sulphate and electric current was passed through the solution. After some time,it was found that the colour of copper sulphate disappeared with the evolution of gas at the electrode. The colourless solution contains:

Of the following,which cannot be obtained by electrolysis of the aqueous solution of their salts?

Explain: Oxidation of $Cl^{-}$ ion is carried out near the anode when electrolysis of aqueous (concentrated) $NaCl$ solution is carried out using an inert electrode.

Which of the following statements is not applicable to electrolytic conductors?
