What change will occur during the electrolysis of brine using carbon electrodes?
Chlorine will be given off at the anode
Oxygen gas will be given off at the anode
Sodium will be deposited at the cathode
The resulting solution, after electrolysis, will be acidic.
The volumes of hydrogen and chlorine given off during the same time are equal
Correct answer is A
Chlorine is discharged as follows:
\(Cl^- \to Cl + e^-\)
\(Cl + Cl \to Cl_{2(g)}\)
This reaction occurs at the anode.
