Which of the following statement is correct about salt bridge?
(a) Forms insoluble precipitate with the electrolytes in the two half-cells
(b) Enhances the flow of electrons by overcoming liquid junction potential
(c) Maintains the electrical neutrality of the two half-cells
(d) Provides the extra ions
Answer is : (c) Maintains the electrical neutrality of the two half-cells
Functions of salt-bridge Complete the cell circuit, maintains electrical neutrality in the solution of two half-cells, prevent diffusion of the solutions from one half-cell to the other.
