Question
During electrolysis, what happens to negative ions in the electrolyte?
Answer
Negative ions move towards the anode during electrolysis. At the anode, they lose electrons in a process called oxidation.
Explanation
This answer is strong because it clearly describes the movement of negative ions and the chemical process occurring at the anode, demonstrating an understanding of electrolysis. The question tests the student's knowledge of ion behavior in electrolysis.
Common mistake
Negative ions move to the anode
Students often think that negative ions travel to the anode during electrolysis
Explain that negative ions (anions) are attracted to the positive electrode, the anode, and are oxidised there, releasing electrons into the external circuit
