Assertion When an electric current is passed through an aqueous solution of sodi
Assertion When an electric current is passed through an aqueous solution of sodium chloride, sodium ions move towards cathode and chloride ions move towards anode. Reason Cathode is a negatively charged electrode and therefore attracts \( \boldsymbol{N} \boldsymbol{A}+ \) ions. Anode is a positively charged electrode and therefore attracts \( C l- \) ions
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Assertion is incorrect but Reason is correct
Step-by-step solution
In electrolysis, cations (Na+) move to the negatively charged cathode, and anions (Cl-) move to the positively charged anode. The Reason correctly states the charge of electrodes and their attraction, which explains the Assertion.
