Question

Assertion: When an aqueous solution of LiCl is electrolyzed using graphite electrodes, as the current flows, the pH of the solution around cathode increases.
Reason: $\stackrel{\ominus }{OH}$ ions forms 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: (A)

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

(increase)Due to the formation of $\stackrel{\ominus }{OH}$ ions at cathode, pOH decreases and pH increases.
