Preferred Label : deliquescence;
IUPAC definition : The process that occurs when the vapour pressure of the saturated aqueous solution
of a substance is less than the vapour pressure of water in the ambient air. When
water vapour is collected by the pure solid compound, a mixture of the solid and liquid
or an aqueous solution of the compound forms until the substance is dissolved and
is in equilibrium with its environment; at this time the vapour pressure of water
over the aqueous solution will equal the partial pressure of water in the atmosphere
in contact with it. A crystalline salt aerosol particle will deliquesce in the atmosphere
when the relative humidity surpasses a characteristic value, the so-called deliquescence
point.;
