Treasure of the Past VI: Standard Potential of the Silver-Silver-Chloride Electrode from 0[degrees] to 95[degrees] C and the Thermodynamic Properties of Dilute Hydrochloric Acid Solutions - Statistical Data Included

Journal of Research of the National Institute of Standards and Technology, March-April, 2001 by Roger G. Bates, Vincent E. Bower

Grateful acknowledgment is made to W. J. Youden for advice and assistance in the statistical treatment of the data, and to G. Valensi for furnishing numerical data not given in his paper. The authors are also indebted to T. F. Young for helpful discussions during the course of the work.

(1.) Figures in brackets indicates the literature references at the end of this paper.

(2.) The calculation of the standard potential from the data of Harned and Ehlers has been examined by Harned and Wright [10], Prentiss and Scatchard [11], Hamer, Burton, and Acree [12], Hills and Ives [13], and Swinehart [14].

(3.) These are the means of the two sets of values given by Harned and Owen, computed from the experimental data in two different ways.

(4.) The data of Gucker and Schminke deviate sharply from the straight line below 0.1 in. This anomalous behavior has not been explained.

(5.) Prentiss and Scatchard [11] have noted that the slopes of the Ilness plotted from the data of Carmody, Roberts. and Harned and Ehlers are nearly the same.

(6.) A similar comparison has been made by King [34].
