|Alfisol, Item 007:|| IExFit, version 3.4
Fit adsorption data based on ion exchange reaction models.
Display solid & liquid & gas phase speciation diagrams as a funciton of pH & redox conditions.
Click on the "Titration" tab to view display a titration simulation and analysis.
In the example below, 20 mM NaH2PO4 was in 30 mL container and titrated with 100 mM HCl and NaOH (shown in black).
The initial pH is given as pH 4.74 (zpt = zero point of titration).
The 1st derivative (1/β) is also shown in green.
Analysis end points are shown in orange.
Note that although IExFit was asked to perform the analysis from pH 0 to 14, the analysis stopped short because the container size (or titrant volume) limitation was set to 30 mL maximum.
