1.	In a galvanic cell, the salt bridge (i) does not participate chemically in the cell reaction (ii) stops the diffusion of ions from one electrolytes to another (ii) is necessary for the occurrence of the cell reaction (iv) ensures mixing of the two elecrolytic solutionsA. (i) and (iii) onlyB. (i) and (ii) onlyC. (iii) and (iv) onlyD. all of these.
Answer» Correct Answer - B Salt bridge keeps the solutions in two half-cells electrically neutral. It prevents transference or diffusion of the ions from one half -cell to the other
