⚠️ Common Exam Traps & Conceptual Pitfalls

Students often assume that swapping the battery leads simply flips the reaction direction and the process continues, overlooking that the original anode and cathode materials are now mismatched for the new polarity; without suitable electrode reactions the electrolysis ceases.

An electrolysis experiment is stopped and the battery terminals are reversed.

Multiple Choice Options

  • A The electrolysis will stop
  • B The rate of liberation of material at the electrodes will increase
  • C The rate of liberation of material will remain the same
  • D Heat will be produced at a greater rate

Step-by-Step Verified Solution

**Answer:** (a) The electrolysis will stop. **Step-by-Step Explanation:** Reversing the battery terminals reverses the direction of current, which reverses the electrolysis process.
