Em. Kuznetsova, MEAN IONIC ACTIVITY-COEFFICIENT AND OSMOTIC COEFFICIENT FOR STRONG ELECTROLYTE-SOLUTIONS IN A WIDE CONCENTRATIONAL RANGE, Russian journal of electrochemistry, 29(9), 1993, pp. 965-970
A new equation with a single fitting parameter is derived for thermody
namic properties of various strong electrolyte solutions whose concent
rations vary over a wide range (0.005 - 10 mol/kg in terms of ionic st
rength). Its efficiency is demonstrated by describing both the mean io
nic activity coefficient (up to gamma+/- approximately 724) and osmoti
c coefficient for a variety of aqueous electrolyte solutions at 298 K.
