Which of the following statements are correct?
a) The electrolysis of aquious NaCl produces hydrogen gas at cathode and chlorine gas at anode,
b) The electrolysis of a `CuSO_(4)` solution using Pt electrodes causes the liberation of `O_(2)` at the anode and the deposition of copper at the cathode.
c) Oxygen and hydrogen are produced at the anode and cathode during the electrolysis of dilute aqueous solution of `H_(2)SO_(4)`
d) All electrolytic reactions are redox reactions

Options

A. Only a is correct
B. a,b are correct
C. a,d are correct
D. a,b,c and d are correct

Answer

D

Explanation

`2H^(+)+2e^(-)rarrH_(2)uarr,` no. of `H^+)` ions decreases, so basic nature increases.
