Which one of the following is not a function of a salt bridge?

A.To allow the flow of cations from one solution to the

B.To allow the flow of anions from one solution to the

C.To allow the electrons to flow from one solution to the✓ Correct

D.To maintain electrical neutrality of the two solutions.

Explanation

Salt bridge consist of electrolyte like 3 4 , , NH KCl KNO Cl . The function of salt bridge is given below- (i) It acts as the electrical contact between two half cells and completes the circuit. (ii) It helps in prevention of accumulation of charges by providing the free path for the migration of ions and to maintain the flow of current in the electrolytic solution. (iii) It also maintains the electrical neutrality in the cell. (iv) It eliminates the junction potential from the cell. Hence, the statement “the electrons to flow from anions from one solution to the other” is incorrect. Thus, th
