Re: Question about PhreeqCI

> We expect that the two solid solutions behave differently. Therefore we
to use each one separately in the same solution. Is there a way to do that
other than putting both solid solutions in one SOLID_SOLUTIONS data block
Phreeq can consider both of them separately.

You can define multiple solid solutions, each with two or more components,
in a single SOLID_SOLUTION data block. I think this is what you want. Each
solid solution will react with the solution to obtain equilibrium. If you
look at the manual (p. 144), the example defines a sulfate and a carbonate
solid solution, which would react independently with the same solution.
