On electrolysing a solution of dilute $H_2SO_4$ between platinum electrodes,the gas evolved at the anode is

Chlorine can be manufactured from

Give the electrolytic reaction of a concentrated aqueous $NaCl$ solution using inert electrodes.

In the electrolysis of aqueous copper sulphate $(CuSO_4)$ using inert electrodes,the gases evolved at the anode and cathode are,respectively:

Mercury cathode can not be used for alkali metals in their fused state because

During electrolysis of $NaCl$ solution,part of the reaction is $Na^{+} + e^- \to Na$. This is termed as
