Electrolysis involves oxidation and reduction respectively at

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

The electrolytic decomposition of dilute sulphuric acid with $Pt$ electrodes in the cathodic reaction is:

Which is the simplest electrolytic cell? Give a detailed note on it.

During the electrolysis of brine,by using inert electrodes,

Assertion : On increasing dilution,the specific conductance keeps on increasing.
Reason : On increasing dilution,the degree of ionisation of a weak electrolyte increases and the number of ions per unit volume decreases.
