Apply Potassium Thiocyanate by spraying from an aerosol-powered spray in a fume cupboard (a fine mist or spray produces better detail than a heavy spray). thiocyanate: translation. Some esters can be prepared by esterification, a reaction in which a carboxylic acid and an alcohol, heated in the presence of a mineral acid catalyst, form an ester and water: The reaction is reversible. Potassium thiocyanate acidic, neutral, or basic? Before the titration an excess volume of a silver nitrate solution is added to the solution A cross-coupling reaction of arylboronic acids with KSCN salt to yield aryl thiocyanates is catalyzed by copper acetate in the presence of 4-methylpyridine serving both as ligand and base under 0.2 MPa of molecular oxygen. Concentrated nitric acid is very corrosive: take great care using the 6molL-1 solution. Relevance. It is an important salt of the thiocyanate anion, one of the pseudohalides.The compound has a low melting point relative to most other inorganic salts. Their names are also helpful in identification.
