In the case of¯VM of ethanol (Fig. S2) there is no extreme on the¯VM− X2curves. It is interesting that V(Fig. S3) and¯VM(Fig. S4) ofwater change as a function of X2in the same way as in the aqueoussolutions of “pure” ethanol [24]. If xBW→ 0 (xBWis the water molefraction in the bulk phase), then¯VM. of water in the solution in thepresence of ethanol (Fig. S4) approaches about 14 × 10−3dm3/mol,which is in accordance with the commonly assumed values in thesolution of “pure” ethanol
