This program calculates the observed rate constant (kobs) for reactions dependent on 1 to 7 protonic states.
XH6 = XH5 = XH4 = XH3 = XH2 = XH = X
The program calculates and plots the pH curves for the protonic states XH6, XH5, XH4, XH3, XH2, XH or X as well as the composite curves and experimental data. This allows you to analyze complex pH dependent reactions manually. Graphs and calculated data can be printed or copied and pasted into applications such as Word. The analysis of pH-dependent kinetics in up to four reactive protonic states has been described (Brocklehurst & Brocklehurst 1988, 256, 556-558). Examples of ionization schemes are given in the support site. The program can also be used to analyze pH dependent change in ppm, absorbance etc simply replace k values with the appropriate pH dependent parameter.
This program can be used to manually analyze pH data which is too complex to analyze using conventional computer fitting programs.
