Activity and Concentration, Transport Numbers and Boundary Potential

Excerpt from Activity and Concentration, Transport Numbers and Boundary Potential: A Dissertation Submitted in Partial Fulfilment of the Requirements for the Degree of Doctor of Philosophy in the University of Michigan, June, 1915 In this investigation of.the relation between activity and concentration, a new form of cell was used which permits of two new methods for measuring transport numbers and a direct method for measuring boundary electromotive force. There are various types of concentration cells, but the type which has excited the most interest and stimulated the greatest amount of experimental and theoretical investigation is that one in which the electrodes are of the same material, but dip into solutions of different concentrations of the same electrolyte. An extensive investigation of such cells was carried out by Hans Jahn. His primary object was to test the existing formulas and theories of solutions when applied to dilute and moderately concentrated solutions of strong electrolytes. From his work Jahn felt justified in concluding. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
