Thallium oxide include two kinds of oxides, thallium(I) oxide and thallium(III) oxide. Tl2O is black powder, however Tl2O3 is brown or dark red powder. Thallous oxide is soluble in water, acid and alcohol. But thallium trioxide is not soluble in water and alkali. Thallium trioxide dissolve in HCl and release chlorine, however release oxygen when dissolve in sulfuric acid.
