Abstract
The structure of hydrated ions of dichloroacetic acid (DCA) is established by electrospraying aqueous solutions of DCA into the vacuum chamber of a mass spectrograph. At an acid concentration of 0.01 mol/L, the number of hydrated ions decreases monotonically with an increase in the degree of their hydration. The resulting mass spectrum provides information on the distribution of hydrated ions in solution, which makes the mass spectrographic method of spraying electrolytes in a vacuum applicable for determining the composition of electrolyte solutions in environmental studies.
