Abstract

Internal friction causes some liquids to flow with less freedom than true solutions of the same density. or with less freedom than water. This is attributed in part to larger particle size and prompts one to propose that when using solutions in which the dissolved substance has not been dispersed and subdivided to single molecular particles that the dissolved particles may be present as com­binations. These combinations may increase to enlarged dimensions with changes in temperature, density. electric charges. etc. Similar conditions are characteristic o starch solutions. The solutions are colloidal and vary in particle size. In some situations the solutions trans­mit suspended particles of starch in more completely dis­persed colloidal starch solutions. One of the more outstanding properties of colloidal solutions is that of viscosity.
