This reaction proceeds very slowly at room temperature. The addition of cobalt chloride as a catalyst produces a green cobalt-tartrate intermediate and copious evolution of oxygen and carbon dioxide.

A recent study published in Light | Science & Applications explored the unique properties of cesium cobalt chloride (Cs 2 CoCl 4) single crystals, emphasizing their potential as dual-functional ...

The white solid turns blue in the presence of water. A similar reversible reaction takes place between anhydrous cobalt(II) chloride (which is blue) and water to produce hydrated cobalt(II ...
