What is the purpose of a salt bridge in a galvanic cell?

Options

  1. ATo facilitate the flow of electrons between the two electrodes.
  2. BTo connect the two half-cells externally.
  3. CTo prevent the mixing of electrolytes in the two half-cells.
  4. DTo increase the cell potential.

Correct answer

C. To prevent the mixing of electrolytes in the two half-cells.

Step-by-step solution

A salt bridge is used to connect the electrolytes of the two half-cells internally and prevent their mixing.
