Which of the followingg are correct?A. Electrolysis of dilute NaOH solution given `H_(2)` at cathode and `O_(2)` at anode.B. Electrolysis of sulphuric acid (dilute or concentrated) gives `H_(2)` at cathode and `O_(2)` at anode.C. Electrolysis of aqueous KF solution gives fluorine at the anodeD. oxidation of copper anode occurs in the electrolysis of aqueous copper sulphate solution using solution copper electrodes.

1.	Which of the followingg are correct?A. Electrolysis of dilute NaOH solution given `H_(2)` at cathode and `O_(2)` at anode.B. Electrolysis of sulphuric acid (dilute or concentrated) gives `H_(2)` at cathode and `O_(2)` at anode.C. Electrolysis of aqueous KF solution gives fluorine at the anodeD. oxidation of copper anode occurs in the electrolysis of aqueous copper sulphate solution using solution copper electrodes.
Answer» Correct Answer - A::D (b) is wrong because electrolysis of concentrated `H_(2)SO_(4)` does not give `O_(2)` at the anode. (c) is wrong because electrolysis of aqueous KF solution gives `O_(2)` at the anode and not `F_(2)`.
