Question

Use of the salt bridge in Galvanic cell is:

• A. to complete the electrical circuit
• B. to separate the cathode solution from anode solution
• C. to reduce electrical resistance
• D. to supply the salts to the chemical reactions taking place in the cell

Answer 1

The correct option is A to complete the electrical circuit

Uses of the salt bridge in Galvanic cell include the following:
(1) To complete the electrical circuit as it provides an electrical contact between the two solutions.
(2) It prevents mixing of electrode solutions.
(3) It maintains electrical neutrality in both the solutions by a flow of ions.
