An automatic capillary viscometer. Part II. Automatic apparatus for viscometric titrations

Abstract

The basic principles of viscometric titrations are considered and examples of applications to a variety of analytical and other determinations are suggested.

An addition to the automatic capillary viscometer described in Part I provides for the introduction of successive measured volume increments of a solvent or solution, admixture with the solution already present in a suspended-level viscometer and the electronic measurement of the flow time including printing-out the results.

By using the new apparatus it is possible expeditiously to determine the B-coefficients of the Jones-Dole equation for the viscosity of electrolytes and the intrinsic viscosity coefficients for solutions of polymers, and to perform a wide variety of acid-base titrations. Practical examples of these determinations are given illustration.
