  • A Chlorine will be given off at the cathode
  • B Oxygen gas will be given off at the anode
  • C Sodium will be deposited at the cathode
  • D The resulting solution, after electrolysis, will be acidic.
  • E The volumes of hydrogen and chlorine given off during the same time are equal
Correct Answer: Option A
Explanation:
Chlorine is discharged as follows:
\(Cl^- \to Cl + e^-\)
\(Cl + Cl \to Cl_{2(g)}\)
This reaction occurs at the anode.
