Cobalt(II) acetate
Encyclopedia
Cobalt acetate is the cobalt
(II) salt of acetic acid
. It may also be found as the tetrahydrate.
It may be formed by the reaction between cobalt oxide or hydroxide and acetic acid:
Cobalt(II) acetate may be reacted with salenH2
to give salcomine
, an oxygen-transport compound:
Cobalt(II) acetate is harmful if swallowed or inhaled. It may cause an allergic skin reaction. Chronic exposure may affect heart, thyroid, lungs, and kidneys.
