Potassium thiocyanate

Colorless monoclinic structure, relative density 1.886, melting point 172.3 ℃, easily soluble in water, and due to a large amount of heat absorption and cooling, also soluble in alcohol and acetone, can be obtained at low temperature hemihydrate crystal (KSCN 0.5H4O), stable at -29.5 ℃ -6.8 ℃, blue when burned to about 430 ℃, but after cooling, it becomes colorless again, such as decomposition when heated to 500 ℃, blood-red ferric thiocyanate is produced in case of ferric salt, but no reaction in case of ferrous salt.
