WitrynaCobalt(II) thiocyanate is an inorganic compound with the formula Co(SCN) 2. It is a layered coordination complex and its trihydrate Co(SCN) 2 (H 2 O) 3 is used in the cobalt thiocyanate test (or Scott test) for detecting cocaine.The test has been responsible for widespread false positives and false convictions. Structure and preparation WitrynaThe SCN - is too weak a base for the formation of HSCN to interfere with the Fe (SCN) 2+ / Fe (SCN) 2+ complexes, so there is no apparent change in the color of the solution. Dish Group 1, 2, 6: KSCN is also added to dish 6 to form the blood red Fe (SCN) 2+ / Fe (SCN) 2+ complexes. Ascorbic acid is then added and reduces the Fe 3+ ion to Fe 2 ...
