The formation quotients of ferrous acetate complexes were determined in aqueous solutions from 50 to 295/degrees/C at ionic strengths of 0.03, 0.1, 0.3, and 1.0 m using sodium trifluoromethanesulfonate as the supporting electrolyte. The potentiometric titrations were carried out in a Teflon-lined concentration cell fitted with hydrogen electrodes. Three complexes, namely, Fe(CH/sub 3/COO)/sub n//sup 2-n/, where n = 1, 2, and 3, were identified by regressional analysis of the data. The relevant thermodynamic quantities were calculated for the first two species.
