Assertion: Sodium metal can be extracted by electrolysis of aqueous NaCl solution, using inert electrodes (Pt electrode). Reason: H2 is produced at cathode. |
Assertion and Reason both are correct statements and reason is the correct explanation for assertion. Assertion and Reason both are correct statements and reason is not the correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement but reason is correct statement. |
Assertion is wrong statement but reason is correct statement. |
Aqueous NaCl solution using Pt electrodes NaCl ⇔ Na+ + Cl- H2O ⇔ H+ + OH- At anode: 2Cl- → Cl2 + 2e- At cathode: 2H+ + 2e- → H2 Na+ interacts with OH- to form NaOH. So, pH of solution increases during electrolysis. |
