The calculator first does a full speciation pKa calculation to determine the species as a function of pH.
Next the solubilty of the neutral species is calculated. To do this you must enter the temperature, solubility units desired and the melting point of the compound.
The calculator then uses the SPARC properties models coupled with the calculated full speciation data to calculate the solubility as a function of pH.
