Input (grade 10): The existence of cobalt (III) chloride, CoCl3, is disputed, although it is listed in some compendia.
Output (grade 6): It can be oxidized to cobalt (III) compounds, although cobalt (III) chloride does not exist. If it is made, it just drops a Cl from CoCl3, making CoCl2 (cobalt (II) chloride) again.
