The pre-moisture in the air is hydrolyzed and smokes. The gas exists as a dimer at around 270°C. It is easily soluble in water and emits a lot of heat. When trivalent gallium in the aqueous solution is above PH6, it exists as oxo acid ion GaO33-GaO2-. Easily soluble in organic solvents such as ether and benzene, and soluble in liquid ammonia to form ammonia complexes.
