Question

What is the function of the salt bridge in an electrochemical cell?

Answer 1

Salt bridge: The salt bridge is used in electrochemical cells to connect the oxidation and reduction half cells of a galvanic cell.

Generally, a salt bridge is composed of strong electrolytes like Potassium chloride(KCl)

Functions of salt bridge:

• A Salt bridge is used to maintain electrical neutrality inside the circuit of a galvanic cell.
• A Salt bridge acts as an electrical connection between two half cells.
• A Salt bridge prevents the diffusion of solution from one cell to the other.
