Question

Assertion: Starting from aq. copper [II] sulphate solution, equations for the reactions at the cathode and anode during electrolysis of aq. $CuS{O}_4$ using active copper electrodes is;
at anode:
$C{u}^{+2}+2e^{-}\to Cu$
at cathode:
$Cu\to C{u}^{+2}+2e^{-}$
Reason: Oxidation always take place at anode and reduction at cathode.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true
• E. Both Assertion and Reason are false

Answer 1

Answer: (D)

Assertion is false but Reason is true

at cathode:
$C{u}^{+2}+2e^{-}\to Cu$
at anode:
$Cu\to C{u}^{+2}+2e^{-}$
