Partial molar volumes [Formula: see text] of the Fe2+, Ni2+, Fe3+, Cr3+, Rh3+, and M(NH3)5OH3+ (M = Cr, Co, Rh, Ir) aqueous ions have been obtained by extrapolation from density measurements at 298.15 K on the perchlorate salt solutions containing added HClO4 where necessary to suppress hydrolysis or oxidation. The values for these high-spin aqua-ions and others in the literature can be represented satisfactorily for ionic charges z = 1 through 4 by[Formula: see text]where [Formula: see text] is the absolute partial molar volume in cm3 mol−1 of Mz+(aq) relative to [Formula: see text] for H+(aq), and r is the Shannon radius in pm of Mz+ with coordination number nc. Volumes of activation ΔVex* for water exchange correlate inversely with [Formula: see text] within the series M2+(aq) and M(NH3)5OH23+(aq) at least, allowing predictions of ΔVex* to be made from [Formula: see text] or the above equation. The physical origin of these correlations is considered.

Partial molar volumes of ammonium aluminium sulfate and potassium aluminium sulfate in DMF-water mixtures (5-20 wt.% of DMF) have been determined from solution density measurements at various temperatures and electrolyte concentrations. The data were evaluated by using Masson equation and the obtained parameters were interpreted in terms of ion-solvent and ion-ion interactions. Both electrolytes have been found to act as the structure makers/promotors in DMF-water systems.
