Antimony trioxide is a white solid insoluble in water. f�pB��f8�w` In the present work, the solubility of both antimony(III) and antimony(V) solids has been examined. The antimony oxide obtained this way is heavily contaminated with lead oxides and further purification is required to obtain a relative pure compound. It is the most important compound prepared from antimony. 1.4 Major uses Elemental antimony is an inflexible metal and therefore has few technical uses. Antimony trioxide is not soluble in water and in nitric acid, not very soluble in diluted H2S04 and HCI but more soluble in these acid concentrates. A mixed arsenic-antimony oxide occurs in the nature as the very rare mineral stibioclaudetite. Reaction of antimony with air. (1) Antimony trioxide is a white powder that is very slightly soluble in water. Antimony is toxic. EC Index Number 234-293-3 When heated, antimony reacts with oxygen in air forming Sb 2 O 3.
