⚠️ Common Exam Traps & Conceptual Pitfalls

Students often mistake the electrochemical equivalent ($Z$) for the total mass deposited, assuming it changes with current or the amount of charge passed. Remember $Z$ is an intrinsic constant for a given material (determined by atomic weight and valency) and does not depend on $I$, $t$, or the quantity of material present.

The electrochemical equivalent of a material depends on __________.

Multiple Choice Options

  • A the nature of the material
  • B the current through the electrolyte containing the material
  • C the amount of charge passed through the electrolyte
  • D the amount of this material present in the electrolyte

Step-by-Step Verified Solution

**Answer:** (a) the nature of the material. **Step-by-Step Explanation:** Electrochemical equivalent depends only on the nature of the material.
