What change will occur during the electrolysis of brine using carbon electrodes?
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: A
Explanation
Chlorine is discharged as follows: \(Cl^- \to Cl + e^-\) \(Cl + Cl \to Cl_{2(g)}\) This reaction occurs at the anode.
