✦ Synopsis

The activity of water in {x 1 AlCl 3 + (1 -x 1 )H 2 O} has been determined by measurement of vapour pressures in the temperature range (300 to 342) K, and the molality range (0.421 to 3.033) mol • kg -1 . The behaviour of the solution is described by the Pitzer model. The [Al(OH)(H 2 O) 5 ] 2+ in the system is calculated by considering the first hydrolysis step in the aluminium chloride solutions.
