Abstract:The basic principles of chemical thermodynamics, as well as the difference of Gibb's free energy, were used to handle chemical equilibria, such as calculations of equilibrium constants and how to understand that only if the sparingly soluble strong electrolyte may keep the product of its ionic concentration constant. The potential of complicated electrode was formulated with the potential of its simple electrode.
Keywords:Chemical equilibria  The difference of Gibb's free energy  Sparingly soluble strong electrolyte  Potential of complicated electrode
