Cobalt (II) propionate is the cobalt salt of propionic acid .

Manufacturing

Cobalt propionate can be prepared by reaction of cobalt (II) hydroxide are shown with propionic acid.

${\displaystyle \mathrm {Co(OH)_{2}+2\ C_{3}H_{5}COOH\ \longrightarrow \ (C_{3}H_{5}COO)_{2}Co+2\ H_{2}O} }$

properties

Cobalt propionate crystallizes as a trihydrate. When heated, the initially wine-red solution turns blue.
