Question
10. A salt bridge is used in a Galvanic cell to eliminate the liquid junction potential. Which of the following conditions guarantees the maximum effectiveness of the salt bridge?
Answer: B
💡 Solution & Explanation
Liquid junction potential arises from the difference in mobilities of diffusing ions. Using a salt like KCl or NH4NO3 where cation and anion mobilities are nearly equal minimizes this potential difference.
