A salt bridge is a laboratory device which maintains electrical neutrality within the internal circuit, connecting the oxidation and reduction half cells of a galvanic cell (voltaic cell). It consists of a U-shaped glass tube filled with agar-agar containing inert electrolyte like KCl or KNO3 which does not react with electrolyte-solutions present in half-cells.
