COMPLEX IONS FORMED WITH THIOCYANATE<br />
(Variations Available)<br />
Characteristic Colors of Cobalt II & Iron III<br />
Adding a thiocyanate  to Cobalt Chloride (aq.) results in a blue color, due to formation of a complex cobalt thiocyanate ion (Co(SCN)2). Adding KSCN to an Iron III solution results in the blood red complex ion Fe(SCN)2+. (Often used for stage blood)
