%X H- acidity function measurements are reported for aqueous hydrochloric acid solutions using a series of phosphorus-containing acid indicators. The relationship between the H-, Ho, and activity (-log10f±C) function for this system was found to be given approximately by                     ½(Ho+H-) &#8776; -log10f±CHCl  A feature of the results is the weak acidity of concentrated hydrochloric acid solutions in respect of the ionization of a negatively charged base, in contrast to the strong acidity of such solutions in respect of the ionization of a neutral base.
