Acid-Base Equilibrium in Aqueous Solutions is a Windows Application which using a recursive procedure calculates pH,
buffer capacity, osmotic pressure, ionic strength, total concentration and the concentrations off all chemical species in
acqueous solution. The solution can have any number components which not form complexes, precipitates or redox
systems. If the ionic strength is<=0.1 the Application calculates as well hydrogen ions activity coefficient, hydrogen
ions activity and -Log(hydrogen ions activity) using the extended Debye-Uuckel equation. Acid-Base Equilibrium in
Aqueous Solutions is available online only. Hardware Minimum Requirements: Video 1024 Width, 600 Height.
Software Requirements: Windows XP with Microsoft.NET Framework 2.0 or Windows Vista.
