Partial molal volumes, V�, at 25�C were measured for sucrose, ascorbic acid and aspirin in the solvents water, formamide, N,N-dimethylformamide and methanol. The dependence of V� on solvent compressibility enabled an estimate to be made of the intrinsic volumes, Vint, of the dissolved non-electrolytes. Effective pressures, Pe, in aqueous electrolyte solutions were calculated from previously determined internal pressure data. Substitution of Pe into the Tait-Gibson equation yielded values of Ve, the volume contraction of water due to electrostriction, which agree well with values obtained by other methods.

We demonstrate that bismuth exhibits no measurable electrocatalytic activity for the nitrogen reduction reaction to ammonia in aqueous electrolyte solutions, contrary to several recent reports on the highly impressive rates of Bi-catalysed electrosynthesis of NH<sub>3</sub> from N<sub>2</sub>.
