MHT CET Chemistry question

Salt bridge is used because it

(A)Maintains the electrical neutrality of the two half cells.Correct
(B)It enhances the flow of electrons by overcoming liquid junction potential.
(C)It provides the lost ions.
(D)It forms insoluble precipitates with the electrolytes in the two half cells.

Answer: (A)

Solution

The ions of the salt bridge migrate into the half cells to balance the charge produced (excess Zn in the anode compartment, loss of Cu in the cathode compartment), keeping both half
