Determination of partial molal volumes of anilinium chloride isopropanol-water mixtures at 30.00$^{circ}$showed a distinct minimum at 0.20 mole fraction isopropanol. This was interpreted as maximum in electrostriction effect and minimum in water structure. The depth in $ar{V}^{circ}$for alcohol-water mixtures was in the order MeOH > i-PrOH > EtOH, which indicated the importance of microscopic structure around ions.
