A Short Textbook of Colloid Chemistry

Abstract

of experimental error the concentration of silver nitrate in the middle compart-Inent remained unchanged during the electrolysis.Results.--The table lists the cation transference numbers obtained at 25.00 ~ • 0.01~ Solvent Moluli~y t+ Water 0.0500 0.463 Water 0.0498 0.465 Water 0.0497 0.462 Water 0.0497 0.462 Acetone 8.57 X 10 -~ 0.449 Acetone 8.57 X 10 -3 0.445 Discussion.--The average value for the silver ion transference number in water is 0.463 ~ 0.003 (99 % confidence limits). This average is not significantly different at the 10% level of significance ("Students t" test) ~ from the value, 4 0.4664, obtained by the moving boundary method. The two results for dilute solutions of silver nitrate in acetone are included to show that the apparatus yields reasonably precise results for solutions of low conductivity.

Effect of electrolyte on the rheological properties of coal‐water mixtures

“…This behavior is in accord with the empirical rule for the critical flocculation concentration for coagulation of hydrophobic colloids, Sollds conc. known as the Schulze-Hardy rule (Jirgensons and Straumanis, 1962), and supports the previous interpretation that the coal particles in a C W M with anionic dispersant are dispersed mainly by electrical repulsive forces arising from negative surface charges. In such a system, the electrolytes in the solution strongly influence the degree of particle dispersion, and thus govern the C W M rheology (Russel, 1978).…”

The Detection and Preparative Separation of Anti-A Hemagglutinins Following Starch Gel Zone Electrophoresis

“…It was postulated that the liquid was extruded because of gel contracture (syneresis). Such a mechanism could have the two-fold effect of forcing intermicellar liquid onto the surface of the gel while at the same time diminishing the number of sites for antibody adsorbance [4]. Some of the experimental data reported in the results is consistent with such a possibility.…”

“…Since relative viscosity is proportional to volume in Einstein's equation (13), the viscosity measurements, like those of light-scattering, did not provide evidence of a change in volume of particles following change in osmotic strength of the medlium.…”
