Abstract:
The formation and stability of UO2(2+)-acetate complexes was studied potentiometrically, at T = 25 degrees C, at different ionic strength, 0 < I < or = 1 mol dm(-3), in aqueous NaCl solutions. Computer analysis allowed us to find the species UO2(ac)+, UO2(ac)2(0), UO2(ac)3- and UO2(ac)3(OH)2-. The dependence on ionic strength of formation constants was taken into account by using both a simple Debye-Hückel type equation and the SIT (Specific ion Interaction Theory) approach. A critical examination of the present results is given together with a comprehensive analysis of literature data.

Ions as Acids and Bases
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:
