Equations were determined for the calculation of the stoichiometric (molality scale) dissociation constant, K m , of lactic acid in aqueous salt solutions at 291.15 and 298.15K from the thermodynamic dissociation constant, K a , of this acid and from the ionic strength, I m , of the solution. The salt alone determines mostly the ionic strength of the solutions considered in...
Single-ion activity coefficient equations were determined for the calculation of the molality-scale dissociation constants, K m , for n-butyric acid in aqueous NaCl or KCl solutions at 298.15K. The activity coefficient equations are of the Huckel type, and K m can be calculated by those for a certain ionic strength from the thermodynamic dissociation constant. The data used for the...
