Total Attempts: 5
Accuracy Rate: 100%
Step-by-Step Solution
The correct option is To complete the electrical circuit and maintain electrical neutrality. A salt bridge contains an electrolyte (like KCl or $NH_4NO_3$) in an agar-agar gel. It prevents liquid junction potential and maintains electrical neutrality in the two half-cells while completing the electrical circuit.
