Zinc Mercury Thiocyanate Crystals

Zinc Mercury Thiocyanate Crystals

Zinc ions in solution with K2Hg(SCN)4 form these crystals.

Zinc in solution can be detected with potassium-mercury thiocyanate (K2Hg(SCN)4). These crystals are characteristic of that reaction. For this test a small crystal of K2(HgSCN)4 is added to the solution. The result are these crystals of ZnHg(SCN)4.
