A salt bridge in chemistry is a laboratory device used to connect the oxidation and reduction half-cells of a galvanic cell, a type of electrochemical cell. As electrons leave one half of a galvanic cell and flow to the other, a difference in charge is established. If no salt bridge was used, this charge difference would prevent further flow of electrons. A salt bridge allows the flow of electrons to maintain a balance in charge between the oxidation and reduction vessels while keeping the contents of each separate. With the charge difference balanced, electrons can flow once again, and the reduction and oxidation reactions can proceed.
Salt bridges at the Department of Biochemistry in Oxford is a project that involves contemporary art works developed for the new Biochemistry building as an art commission, part of a major capital project. A science consultant worked in partnership with the department’s art consultant
