NEET Chemistry Electrolytic Cells MCQ Question
Consider a diagram of an electrolytic cell with two copper electrodes immersed in an aqueous copper sulfate solution and connected to a DC power supply. Which of the following correctly identifies the process occurring at the anode?
Copper metal is oxidized to Cu2+ ions.
Cu2+ ions gain electrons to form copper metal.
Water is reduced to produce hydrogen gas.
Sulfate ions are oxidized to form sulfur trioxide.
Correct Answer
Detailed Explanation
In an electrolytic cell with copper electrodes, the anode is where copper metal is oxidized to Cu2+ ions, as per the reaction Cu(s) → Cu2+(aq) + 2e–.
