Henry's Constant as a Function of pH

This will perform a Henry's constant calculation as a function of pH in the presence of suspended solids.

If you want to calculate the Henry's constant as a function of pH without solids, simply set the solids concentration to zero.

If you wish only to carry out Henry's constant as a function of pH with no solids just choose a solid concentration of 0.0

You determine the nature of the suspended solids by selecting:

•Total Solids e.g 0.001 g/L

•Composition:

% sand,clay,organic

•Sand surface area

•Clay composition:

% swelling, non-swelling

•Organic type

e.g. generic_organic

•Metals in solution that may

alter binding

Molarity of charge 1,2,3 ions

•Units for the Henry's constant

When the calculate button is pressed you will see a tabbed output. The tabs and their content are:

•Rxns: these are the graphical depiction of the microconstants and their calculated micro pKa's.

•Henry Plot: this is a plot of the Henry's Constant as a function of pH.

•Data Table: this is a table of numerical Henry's constant as a function of pH.
