Abstract
A potentiometric study on the protonation constants of pyrophosphate [ diphosphate(4-)] and triphosphate(5-) in aqueous solutions of Me4NCl, NaCl and KCl at different ionic strengths (0 less-than-or-equal-to/les s-than-or-equal-to 0.75 mol l-1) and temperatures (5 less-than-or-equa l-to T less-than-or-equal-to 45-degrees-C) is reported; medium effects are interpreted by a complex formation model.
