The arsonium cation is a positively charged polyatomic ion with the chemical formula AsH+
4. An arsonium salt is a salt containing either the arsonium (AsH+
4) cation, such as arsonium bromide (AsH+
4Br−
) and arsonium iodide (AsH+
4I−
), 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 Ph
4As+
Cl−
(CAS: 123334-18-9 , hydrate form) and the zwitterionic compound arsenobetaine.
