Question
What products are formed at the anode during the electrolysis of an aqueous solution containing chloride ions?
Answer
Chlorine gas is produced at the anode during the electrolysis of an aqueous solution containing chloride ions.
Explanation
This answer is strong because it directly addresses the specific ions present in the solution and the expected product at the anode. The question tests the understanding of electrolysis and the behavior of halide ions.
Common mistake
Confusing Halide Products
Students often predict that oxygen is produced at the anode instead of chlorine, bromine, or iodine when halide ions are present.
Remember that when halide ions are present, the corresponding halogen (chlorine, bromine, or iodine) is produced at the anode instead of oxygen.
