The cell used for the electrolysis of fused $NaCl$ is

Molten $CuCl_2$ is electrolysed using platinum electrodes. The reaction occurring at the anode is:

Which among the following is common for electrolysis of molten $NaCl$ and aqueous $NaCl$?

"Products obtained near the electrodes by electrolysis depend on the electrodes" - explain by suitable examples.

During the electrolysis of $NaCl$ solution,$H_2$ gas is liberated at the cathode when a $Pt$ electrode is used,whereas sodium amalgam is formed when a $Hg$ cathode is used. What is the reason for this?

The electroplating of $Cr$ is undertaken because:
