Viscosimetric studies of aqueous solutions of salts of carboxylic acids

Viscosities and densities of aqueous solutions of sodium salts of monocarboxylic acids (formic, acetic, propionic, valeric, chloroacetic, trichloroacetic, glycolic, phenylacetic) and dicarboxylic acids (oxalic, malonic, succinic, glutaric, adypic, pimelic, dl-tartaric, dl-malic, maleic, fumaric, o-phthalic) have been measured in the concentration range 0.02-0.1 mol·dm− 3 at 298.15 K. The effect of hydrolysis of salts on viscosimetric data describing the objects under study was considered. The modified Jones-Dole equation taking into account the phenomenon of hydrolysis was proposed. The viscosity B coefficients for these electrolytes were determined.
