Question
Which of the following is inert in an electrochemical cell?
Correct Answer
Option B is the correct answer.
Detailed Explanation
The salt bridge contains an inert electrolyte (like KNO₃ or KCl) that does not react with the cell components. Its purpose is to maintain electrical neutrality by allowing ion migration without participating in the redox reactions.
Hint
Its role is to complete the circuit without interfering with the chemistry.
