Solutions with high elemental iodine concentration such as tincture of iodine are capable of causing tissue damage if use for cleaning and antisepsis is prolonged.
Rubidium triiodide is an orthorhombic black crystal, isomorphic to caesium triiodide, with space group Pnma, unit cell parameters a = 1090.8 pm, b = 665.5 pm, c = 971.1 pm. [2] Upon heating to 270 °C, the rubidium triiodide decomposes into rubidium iodide and elemental iodine. [1] It is soluble in ethanol and decomposes in ether. [1]
Iodine compounds are compounds containing the element iodine. Iodine can form compounds using multiple oxidation states . Iodine is quite reactive, but it is much less reactive than the other halogens.
