Zinc Mercury Thiocyanate Crystals
Zinc ions in solution with K2Hg(SCN)4
form these crystals.
Transmitted Off Crossed Polarized Light Illumination
Definition/Function:
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.
