For a cell to work, which of the following condition(s) become necessary ___________?
Correct answer: D. All above three conditions are necessary
- A. Two electrodes of different meta's should be inserted in the electrolyte, not touching each other
- B. Electrolyte must chemically react with one of the electrodes
- C. Electrolyte liquid or paste should be conducting
- D. All above three conditions are necessary
Explanation
A conventional cell needs separated electrodes, an ionically conducting electrolyte, and a chemical reaction that produces charge separation. The three statements describe these operating requirements, so all are included.
