Foundations of Colloid Science, Volume 2While Volume I stands as an essentially complete advanced textbook of colloidal science, Volume II extends the material to include important new areas, and develops some of the topics in much greater depth. An introductory chapter on the theory of liquids describes the concept of correlation functions and the use of Fourier transforms to analyse the scattering of light and neutrons by colloidal systems. Absorption is given detailed coverage and a chapter on electrokinetics introduces a new approach to time-dependent processes in the double layer. The principles of double layer theory are also used to review the behavior of thin films and emulsions. A final chapter on the rheology of colloidal suspensions calls on many of the concepts developed earlier to bring some cohesion to this important and rapidly developing field. |

It was formerly assumed that a type ( ii ) electrolyte could be identified by its effect
on the plot of surface charge versus p . d . i concentration . If the curves for
different electrolyte concentrations ( Fig . 6 . 7 . 1 ) showed a common intersection
