(a)Salt bridge is required for the mixing of the solutions in the two half cells.
(b)Salt bridge allows current to flow between the half cells without mixing the solutions
(c)Salt bridge enhances the rate of the reaction
(d)Salt bridge consists of a non-electrolyte in a gel.
Answer
Answer: B ✓ checked by 4AB · confidence high
Explanation
A salt bridge completes the circuit by carrying ions between the half-cells while preventing the two solutions from mixing; it contains an electrolyte (KCl/KNO₃) in a gel and does not alter the reaction rate.
