In a galvanic cell, the salt bridge.

Options

A. does not participate chemically in the cell reaction
B. stops the diffusion ofions from one electrode to another
C. is necessary for the occurrence of the cell reaction
D. ensures mixing of the two electrolytic solutions.

Answer

A, B

Explanation

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.
