The Electromotive Behaviour of Single Zinc Crystals

To NATURE of Jan. 12, 1929, p. 49, Paul A. Anderson communicated some measurements of his on the potentials of single crystals of zinc. The investigation of a possible change of the electrochemical potential with the changing density of zinc atoms on different planes of the crystal was also the aim of an experimental research commenced in October 1928 in the Physicochemical Laboratory of the University of Latvia, in Riga, and is now in progress. The results obtained here do not agree with those of Anderson in so far as no difference could be found in the potentials of different, artificially prepared planes of single crystals of zinc against a neutral zinc sulphate solution. It must be admi…
