Arsenious acid, also known as arsenous trioxide or arsenic trioxide, is an inorganic compound with the chemical formula H₃AsO₃. It is a weak acid and exists primarily in aqueous solution, where it can act as a source of arsenite ions (AsO₃³⁻). This compound is characterized by its colorless, odorless appearance in solution, and it is highly soluble in water. Arsenious acid is known for its toxicity and is classified as a carcinogen, posing significant health risks upon exposure. It is often used in various industrial applications, including glass manufacturing, as a wood preservative, and in the production of certain pesticides. In terms of chemical behavior, arsenious acid can undergo oxidation to form arsenic acid (H₃AsO₄) and can participate in redox reactions. Its handling requires strict safety measures due to its hazardous nature, and it is subject to regulatory controls in many countries.
