✦ Synopsis

An attempt has been undertaken to apply viscosimetric measurements for the examination of incomplete dissociation of symmetric electrolyte solutions. For this purpose precise measurements of the viscosity and density of dilute aqueous solutions of monocarboxylic acids (formic, acetic, propionic and valeric) have been conducted at 298.15 K. Modified Jones-Dole equations have been proposed for incompletely dissociated electrolyte solutions of 1-1 type. The data have been analysed taking into account dimerization of carboxylic acids. The B coefficients for all chemical species in the solution have been determined.

An increasing number of carbon atoms in unsaturated carboxylic acids gave rise to increased distribution coe&ients in sulphate and acetate solutions, both on styrene-divinylbenzene resins and on anion-exchange resins. On the non-ionic resins the double bond led to a large decrease in the retention v

## Abstract Gum ghatti contains a soluble gum and an insoluble gel which partially dissolves on boiling. Maceration of the gel in water gives a perfectly stable dispersion which for practical purposes behaves as a solution. The viscosity of the gel dispersion is __ca__ 10–30 times that of the solub
