WebSorption behavior describes the ability of a hygroscopic product to absorb or release water vapor from or into the air until a state of equilibrium is reached. Adsorption means uptake of water vapor. Desorption means water vapor release. A sorption isotherm is the graphic representation of the sorption behavior of a substance. WebSolid sodium hydroxide is hygroscopic, which means that it absorbs moisture from the atmosphere. Once it has a little moisture it also absorbs carbon dioxide which is always present in air. The reaction is: 2 NaOH (s) + CO 2 (g) →Na 2 CO 3 (aq) + H 2 O (l) This means that solid reagent grade sodium hydroxide is not pure enough to weigh and ...
