Description. Cobalt(II) chloride (CoCl 2) is the most common cobalt compound found in laboratories. The dramatic color change of blue-purple Cobalt(II) chloride to a rose color when hydrated makes CoCl 2 an excellent indicator for water in dessicants.
This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of cobalt. For each compound, a formal oxidation number for cobalt is given, but the usefulness of this number is limited for p-block elements in particular.
