Partial molar free energy of an element A in solution is same as its Correct Answer Chemical potential
The chemical potential is nothing but the partial molar Gibbs free energy.$${\mu _i} = \left( {\frac{{\partial nG}}{{\partial {n_i}}}} \right)d{n_i}$$
By which we can tell whether the chemical equilibrium is reached by a system or not.
