%X The apparent molar volumes of aqueous ammonia, ammonium chloride, aniline and anilinium chloride are measured up to 2 mol l-1 at 25°C by a combination of pyknometric and dilatometric methods. The apparent molar volume  f°V of undissociated ammonia at infinite dilution is found to be 24.85±0.02 cm3 mol-1, and that of NH4Cl is 35.71±0.02 cm3 mol-1. The volume change on ionization for the standard states &#916;V° is -29.07±0.04 cm3 mol-1. For aniline the values are: f°V(PhNH2) 89.30, f°V(PhNH3Cl) 102.74 and &#916;V° -26.49±0.05 cm3 mol-1.
