Paper, 'Electrolytic conduction in relation to molecular composition, valency and the nature of chemical change: being an attempt to apply a theory of "residual affinity"' by Henry E [Edward] Armstrong

Description

Armstrong writes: 'In my recent address to the Chemical Section of the British Association at Aberdeen, I have specially called attention to the “affinity” of negative elements—chlorine, oxygen, sulphur, &c.—for negative elements; and I have sought to show that the formation of so-called molecular compounds is largely, if not entirely, an outcome of this peculiarity of negative elements. I have also ventured to suggest “that in electrolysing solutions, the friction arising from the attraction of the ions for each other is perhaps diminished, not by the mere mechanical interposition of the neutral molecules of the solvent—in the manner suggested by F Kohlrausch—but by the actual attraction exercised by these molecules upon the negative ion in virtue of the affinities of the negative radicles.”'

Annotations in pencil and ink. Includes one page of graphs of experimental results.
