WebCopper(II) ion oxidizes thiocyanate, according to the following highly simplified equation: 2Cu 2+ + 2SCN – → 2Cu + + (SCN) 2. This reaction does not occur in its bare form, as presented above, it always leads to formation of copper(I) thiocyanate, so a somewhat better approximation is: 2Cu 2+ + 4SCN – → 2CuSCN + (SCN) 2 WebMercury(II) ion forms insoluble Hg(SCN) 2, but when excess thiocyanate is used, then a colorless complex ion is formed, which can be written as Hg(SCN) 4 2–. The ammonium salt of this ion is soluble in water. This explains why mercury(II) chloride easily dissolves in excess amount of a solution of ammonium thiocyanate.
