VISCOSITY OF AQUEOUS SOLUTIONS OF FORMIC, CYANOACETIC AND OXALIC ACIDS.

Viscosities of aqueous solutions of formic, cyanoacetic and oxalic acids have been measured at 35°. The viscosity of these solutions is represented quite well by either of the two equations proposed by the authors, but the values of viscosity constants are not of the expected order. The results are also represented by the Jones and Dole equation, but the constants have no theoretical significance for weak electrolytes.
