Description and Uses
Mercury thiocyanate is a white, odorless powder. Molecular weight= 316.79; Freezing/Melting point=about 165℃ (decomposes). Slightly soluble in cold water.
Mercury(II) thiocyanate is used as a precursor to potassium tris(thiocyanato)mercurate(II) and cesium tris(thiocyanato)mercurate(II). It is also used in the determination of chloride ions in water by UV-visible spectroscopy. Further, it acts as a catalyst for the addition of thiocyanic acid to alkynes.
