Specific Ion Interaction Theory
(SIT) To correct stability constants for changes in ionic
strength and to estimate SIT parameters. Contains an editable database of
published SIT parameters. Also to interconvert : Molarities (c) and Molalities (m) lg K(c) and lg K(m). 

Electrolytes:To calculate electrolyte activity coefficients, osmotic coefficients and activity of water using Pitzer and the LinTsengLee equations. Also calculate ionic activity coefficients using the MilleroPitzer method.  
Acidbase equilibria To
calculate acidbase equilibria in electrolyte solutions and seawater. To
also calculate H+ activity coefficients for pH correction in different ionic
media.The concept of apparent equilbrium constants is used to calculate equilibrium constants of more than 260 mono and polycarboxylic acids with background ions 

.O_{2} solubility in water, 22 electrolyte solutions, natural fluids and seawater as a function of temperature, concentration and salinity. 

Temperature dependence of lg K
using 8 thermodynamic equations. Full statistics are included.
