Which of the following is true for an acid-base concentration cell such as the one used by the pH meter?
Show Hint
In electrochemical cells, current flows from low concentration to high concentration to balance the charge difference.
Updated On: Mar 30, 2025
- Current always flows towards the more acidic solution
- Current always flows towards the more basic solution
- Current always flows towards the more neutral solution
- Current always flows away from the more neutral solution

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
In an acid-base concentration cell, the current always flows from the lower concentration solution to the higher concentration solution, which in this case is the more acidic solution.
