Step 3: Run Aqueous Speciation - Tab: f(pH) Solids

Click on the "f(pH) Solids" tab to view the distribution of each of the solids formed as a function of pH.
In the example below, we see the solids formed for 20 mM Mg(2+) + 10 mM CO3(2-) + 10 mM PO4(3-) as a function of pH.

The second image below shows the log(SI) values for an exercise involving Fe(3+) ions,
where, log(SI) = log (saturation index).
