In this paper the physical meaning of the single parameter in simplified Pitzer(1980) model is discussed. The parameter is found proportional to the hydration number of the electrolyte
therefore the correlation equation is obtained from which this parameter can be evaluated from ionic radii. The temperature dependence of the parameter is also verified by predicting the excess enthalpy of the electrolyte aqueous solutions at 373.15K.
