salt bridge (redirected from Saline bridge)

salt bridge [′sȯlt ‚brij]

(physical chemistry)

A bridge of a salt solution, usually potassium chloride, placed between the two half-cells of a galvanic cell, either to reduce to a minimum the potential of the liquid junction between the solutions of the two half-cells or to isolate a solution under study from a reference half-cell and prevent chemical precipitations.
