From electromotive-force measurements of the cell without liquid junction:
Pt; [H.sub.2], HCl (m), AgCl; Ag
through the range 0[degrees] to 95[degrees] C, calculations have been made of (1) the standard potential of the silver-silver-ehloride electrode, (2) the activity eoeffieient of hydrochloric aeid in aqueous solutions from m (molality) = 0 to m=0.1 and from 0[degrees] to 90[degrees] C, (3) the relative partial molal heat content of hydrochloric acid, and (4) the relative partial molal heat capacity of hydrochloric acid.
The extrapolations were made by the method of least squares with the aid of punch-card techniques. Data from at least 24 ...
