gallium(ii) chloride

Description:
Gallium(II) chloride, with the chemical formula GaCl₂, is an inorganic compound characterized by its formation of gallium in the +2 oxidation state. It typically appears as a white or yellowish solid and is known for its hygroscopic nature, meaning it readily absorbs moisture from the air. Gallium(II) chloride is soluble in polar solvents, such as water and alcohols, but has limited solubility in non-polar solvents. The compound can be synthesized through various methods, including the reaction of gallium with chlorine gas at elevated temperatures. Gallium(II) chloride exhibits interesting properties, including potential applications in materials science and as a precursor for other gallium compounds. However, it is less commonly encountered than its more stable gallium(III) counterparts. Due to the relatively unstable nature of the +2 oxidation state in gallium, GaCl₂ can readily oxidize to gallium(III) chloride in the presence of air or moisture, making it important to handle it under an inert atmosphere to maintain its integrity.
