Barium Arsenite

Barium arsenite is a chemical compound with the molecular formula BaAsO3. It is a white crystalline powder that is insoluble in water but soluble in acids. Barium arsenite can be prepared by reacting barium carbonate with arsenic trioxide.

Barium arsenite has been used as a pesticide and insecticide due to its toxic properties, but its use has been largely discontinued due to its harmful effects on human health and the environment. Exposure to barium arsenite can lead to skin and eye irritation, respiratory problems, and various types of cancer.

In terms of its chemical properties, barium arsenite is a source of both barium and arsenic ions. It undergoes thermal decomposition at high temperatures to form barium oxide and arsenic trioxide. It also forms a variety of salts and complexes with other ions and molecules, such as potassium arsenite and copper (II) arsenite.

Overall, barium arsenite is a highly toxic and hazardous substance that should be handled with extreme caution and avoided whenever possible.
