3  * Definitions for the %HMWSoln ThermoPhase object, which
4  * models concentrated electrolyte solutions
5  * (see \ref thermoprops and \link Cantera::HMWSoln HMWSoln \endlink) .
6  *
7  * Class %HMWSoln represents a concentrated liquid electrolyte phase which
8  * obeys the Pitzer formulation for nonideality using molality-based
9  * standard states.
10  *
11  * This version of the code was modified to have the binary Beta2 Pitzer
12  * parameter consistent with the temperature expansions used for Beta0,
13  * Beta1, and Cphi.(CFJC, SNL)
