WebSodium thiocyanate (NaSCN) has a wide range of applications. Is commonly used in the medical field for the synthesis and isolation of antibiotics; in the textile field, the fiber is used as a solvent extraction agent for polyacrylonitrile fibers; in the field of crop protection, the plant defoliant is used as a certain plant defoliant and a synthetic raw material of some … Sodium thiocyanate (sometimes called sodium sulphocyanide) is the chemical compound with the formula NaSCN. This colorless deliquescent salt is one of the main sources of the thiocyanate anion. As such, it is used as a precursor for the synthesis of pharmaceuticals and other specialty chemicals. Thiocyanate salts are typically prepared by the reaction of cyanide with elemental sulfur:

WebScandium is very much a late starter compared to many of the other elements, due to its relatively low occurrence and the difficulty in obtaining it from its ores. For example, it wasn't until the 1960s when the first pound, or 450 grams, of high purity scandium was obtained. Compounds of scandium find use in organic chemistry. WebThe formula for mercury (I) chloride is Hg2Cl2. Unlike other transition metals, the 1+ cation of mercury has the formula Hg22+ and behaves like a polyatomic ion. What is the formula for mercury (II) nitride? The formula for mercury (II) nitride is Hg3N2. Mercury has a 2+ charge, as indicated by the roman numeral, and nitride has a 3- charge.
