Data for Aqueous H2SO4

The System

Sources of the data reproduced here are listed by Clegg et al. (1994), and by Clegg and Brimblecombe (1995) who also describe fits of the E-AIM model. Data from recent studies are also tabulated on these pages.

S. L. Clegg, J. A. Rard, and K. S. Pitzer (1994) J. Chem. Soc. Faraday Trans. 90, 1875-1894.

The values listed in the tables are based upon those used in the fits of the model. However, they have been normalised for each type of measurement so that the maximum weight for a data point in each table is always unity. Points given zero weight are those which either appear to be in error, or are used for comparison only (and were not fitted).

The Data
