Foundations of Colloid Science, Volume 1Liquid suspension systems are the basic ingredients of paints, detergents, biological cells, and countless other systems of scientific and technological importance. This book presents the fundamental physical and chemical concepts necessary to the understanding of these systems and of colloid science in general. New ideas are introduced carefully and formulae are developed in full, with exercises to help the reader throughout. The frequent references to the many applications of colloid science will be especially helpful to beginning research scientists and people in industry, medicine and agriculture who often find their training in this area inadequate. Integrating developments from the time of colloid science's infancy forty years ago to its present state as a rigorous discipline, this intelligently assembled work elucidates a remarkable range of concepts, techniques, and behaviors. |

2 Observation of coagulation behaviour There are two levels on which
coagulation can be studied : the microscopic and the macroscopic . At the
microscopic level we would seek to follow the individual collisions between pairs
of particles , to ...

The rate of coagulation is then determined by the rate of diffusion of particles
towards one another due to Brownian motion . The electrolyte concentration at
which slow coagulation gives way to rapid coagulation can be determined ...
