Glenn T. Hefter Solubility, Solubility data series The apparatus used is described in detail in [1]. The method involves the introduction of solute vapor (1) into liquid (2) by bubbling air through liquid (1) using a recirculating pump in a closed system. After solubility equilibrium was attained an aliquot of the saturated aqueous solution was withdrawn and analyzed by solvent extraction - UV spectrophotometry.
