ALTERNATE FORMS OF SALT BRIDGES
Alternate approaches to building salt bridges for electrochemical cells are reviewed. Materials such as filter paper, cotton, semi-micro tubes, human beings, Soil Moist, vials, etc. have been used to construct salt bridges in instructional laboratory settings. Of these, a human salt bridge involving 1500 people (Silverman and Bunn, 1992) is an interesting example in terms of bringing the concept of salt bridges to life and making laboratory chemistry meaningful.
