Conductivity studies on aqueous solutions of stereoisomers of tartaric acids and tartrates. Part III. Acidic tartrates

Conductivity measurements on aqueous solutions of sodium hydrogen tartrate and potassium hydrogen tartrate were performed in the temperature range 5-35 degrees C. By including the dissociation equilibria, the experimental conductivities of the acidic salts can be well described using equivalent limiting conductivities of the bitartrate anion lambda(infinity)(HTar(-)) and the tartrate anion lambda(infinity) (1/2 Tar(2-)) when applying the Quint and Viallard equations for unsymmetrical electrolytes.
