Question

Assertion: Impure copper anode will disappear and pure copper depositions will be seen on cathode.

Reason: During electrolysis, electicity flows and appropriate ions deposits at corresponding electrodes.

• 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: (A)

Both Assertion and Reason are true and Reason is the correct explanation of Assertion

At anode, oxidation happens so its called oxidising electrode.
at cathode reduction happens so it is called reducing electrode.
If XY compound is electrolysed in cell then
at anode:
$Y^{-}\to Y+e^{-}$
at cathode:
$X^{+}+e^{-}\to X$
So, during electrolysis, electicity flows and appropriate ions deposits at corresponding electrodes.
