Question
What is produced at the anode during the electrolysis of an aqueous solution if no halide ions are present?
Answer
Oxygen gas is produced at the anode during the electrolysis of an aqueous solution if no halide ions are present.
Explanation
This answer is strong because it directly addresses the prediction made in the learning objective regarding the products of electrolysis in the absence of halide ions. It tests the student's understanding of the electrolysis process and the conditions affecting the products formed.
Common mistake
Misunderstanding Anode Products
Students often predict that oxygen is produced at the anode in all cases without considering the presence of halide ions.
Students should remember that oxygen is produced at the anode unless halide ions are present, in which case chlorine, bromine, or iodine will be produced instead.
