Applications
DescriptionThis deep red-violet salt is obtained as the tetrahydrate by crystallization of an aqueous solution of cobalt carbonate in thiocyanic acid. It is very deliquescent and gives a dark blue concentrated solution which turns pink upon dilution. It gives blue solutions in many organic solvents.
UsesCobalt(II) thiocyanate is best known for the cobalt thiocyanate test (or Scott test), which is a proven screening test for the presence of cocaine.
