In a galvanic cell, the salt bridge

Answer»

does not participate chemically in the cell reaction
stops the DIFFUSION ofions from one ELECTRODE to another
is necessary for the occurrence of the cell reaction
ensures mixing of the two electrolytic solutions.

Solution :Salt BRIDGE does not participate chemically in the cel reaction because the amount of electrolyte in the bridge REMAINS unchanged. It keeps the solutions in the two half-cells electrically neutral. It simply allos the PASSAGE of ions through it. It prevents transference or diffusion of ions from one half-cell to the other.
