An arsonium salt is a salt containing either the arsonium ({{chem|AsH|4|+}}) cation, such as arsonium bromide ({{chem|AsH|4|+|Br|-}}) and arsonium iodide ({{chem|AsH|4|+|I|-}}), which can be synthesized by reacting arsine with hydrogen bromide or hydrogen iodide.[1]. Or more commonly, as organic derivative such as the quaternary arsonium salts {{chem|Ph|4|As|+|Cl|-}} (CAS: [123334-18-9], hydrate form) and the zwitterionic compound arsenobetaine.
