- * Computation of the electric properties of phases
- *
- * ### Treatment of the phase potential and the electrochemical potential of a species
- *
- * The electrochemical potential of species @f$ k @f$ in a phase @f$ p @f$, @f$ \zeta_k @f$,
- * is related to the chemical potential via the following equation,
- *
- * @f[
- *            \zeta_{k}(T,P) = \mu_{k}(T,P) + z_k \phi_p
- * @f]
- *
- * where  @f$ \nu_k @f$ is the charge of species @f$ k @f$, and @f$ \phi_p @f$ is
- * the electric potential of phase @f$ p @f$.
- *
- * The potential  @f$ \phi_p @f$ is tracked and internally stored within the
- * base ThermoPhase object. It constitutes a specification of the internal state
- * of the phase; it's the third state variable, the first two being temperature
- * and density (or, pressure, for incompressible equations of state). It may be
- * set with the function, ThermoPhase::setElectricPotential(), and may be
- * queried with the function ThermoPhase::electricPotential().
- *
- * Note, the overall electrochemical potential of a phase may not be changed
- * by the potential because many phases enforce charge neutrality:
- *
- * @f[
- *            0 = \sum_k z_k X_k
- * @f]
- *
- * Whether charge neutrality is necessary for a phase is also specified within
- * the ThermoPhase object, by the function call
- * ThermoPhase::chargeNeutralityNecessary(). Note, that it is not necessary for
- * the IdealGas phase, currently. However, it is necessary for liquid phases
- * such as DebyeHuckel and HMWSoln for the proper specification of the chemical
- * potentials.
- *
- * This equation, when applied to the @f$ \zeta_k @f$ equation described
- * above, results in a zero net change in the effective Gibbs free energy of
- * the phase. However, specific charged species in the phase may increase or
- * decrease their electrochemical potentials, which will have an effect on
- * interfacial reactions involving charged species, when there is a potential
- * drop between phases. This effect is used within the InterfaceKinetics and
- * EdgeKinetics kinetics objects classes.
- *
- * ### Electrothermochemical Properties of Phases of Matter
- *
- * The following classes are used to compute the electrical and
- * electrothermochemical properties of phases of matter. The main property
- * currently is the dielectric constant, which is an important parameter for
- * electrolyte solutions. The class WaterProps calculate the dielectric
- * constant of water as a function of temperature and pressure.
- *
- * WaterProps also calculate the constant A_debye used in the Debye Huckel and
- * Pitzer activity coefficient calculations.
