Beschreibungen/Notizen

• The formation constants of Li +, N +, K +, Mg 2+ and Ca 2+ phenoxyacetate complexes were determined potentiometrically using an (H +)-glass electrode at 10, 25, 37 and 45°C, at several ionic strengths, in the range 0.04⩽ I⩽ 0.9 mol 1 −1. Simple empirical equations for the dependence of the formation constants on ionic strength were derived. From the temperature coefficients, estimates of Δ H o and Δ S o were obtained.
