Question

Assertion: Sodium cannot be obtained by the electrolysis of aqueous solution of NaCl using Pt electrodes.

Reason: In the aqueous NaCl solution, $H_{2}O$ will get reduced during electrolysis.

• 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

Correction : in question sodium cannot be obtained. In aqueous solution , it is $H_{2}O$ which is reduced.
$2H_{2}O+2e^{-}\to 2H_2+2\stackrel{\ominus }{O}H$
