The function(s) of salt bridge in a cell is/are — Electrochemistry Chemistry Question

💡 Solution & Explanation

A salt bridge serves critical roles in a galvanic cell: it completes the inner electrical circuit by allowing ions to migrate, it keeps the two half-cell solutions physically separated (preventing rapid mechanical mixing, or "departing" them), and it maintains macroscopic electrical neutrality in both compartments by providing a steady flow of balancing counter-ions. It does not dictate or maintain the standard electrode potential itself. Therefore, correct answer is B,C,D.
