Chemical Properties
White powder. Soluble in hydrochloric acid and alkali tartrate solutions; insoluble in alcohol, ether, and water.
Physical properties
It is precipitated by hydrolysis when concentrated solutions of antimony trichloride in water or hydrochloric acid are diluted. Because other chloride oxides, e.g., Sb4O5Cl2, also form, reaction conditions must be controlled carefully. Antimony chloride oxide is an intermediate in the production of antimony salts and is used in smoke-producing agents.
