Question: Which of the following ions is reduced at the cathode during electrolysis of copper(II) sulfate solution? (2020)

Options:

Correct Answer: Cu²⁺

Exam Year: 2020

Solution:

Cu²⁺ ions are reduced to copper metal at the cathode during the electrolysis of copper(II) sulfate solution.

Which of the following ions is reduced at the cathode during electrolysis of copper(II) sulfate solution? (2020)

Which of the following ions is reduced at the cathode during electrolysis of copper(II) sulfate solution? (2020)

Step 1: Understand what electrolysis is. It is a process that uses electricity to cause a chemical change.
Step 2: Identify the solution being electrolyzed. In this case, it is copper(II) sulfate solution.
Step 3: Know that during electrolysis, ions move to different electrodes. The cathode is where reduction occurs.
Step 4: Identify the ions present in copper(II) sulfate solution. The main ions are Cu²⁺ (copper ions) and SO₄²⁻ (sulfate ions).
Step 5: Remember that reduction means gaining electrons. At the cathode, Cu²⁺ ions gain electrons.
Step 6: Write the reduction reaction: Cu²⁺ + 2e⁻ → Cu (this means copper ions are turned into copper metal).
Step 7: Conclude that Cu²⁺ ions are the ones reduced at the cathode during this process.
