Lead(II) thiocyanate

Lead(II) thiocyanate is a compound, more precisely a salt, with the formula Pb(SCN)2.It is a white crystalline solid, but will turn yellow upon exposure to light. It is soluble in water and can be converted to a basic salt (Pb(CNS)2*Pb(OH)2 when boiled. Salt crystals may form upon cooling. Lead thiocyanate can cause lead poisoning if ingested and can adversely react with many substances. It has use in small explosives, matches, and dyeing.

Lead thiocyanate can cause lead poisoning if ingested and can adversely react with many substances. It has use in small explosives, matches, and dyeing. Lead(II) thiocyanate is reasonably soluble at room temperature, thus it may be difficult to identify in a solution with low concentration of lead(II) thiocyanate. Although it has not been confirmed by other sources than the author of this article, experiments show that even if there is no precipitation of lead(II) thiocyanate in the solution, crystals of the salt may form. Lead(II) thiocyanate can be formed from the acidification of Lead Nitrate Pb(NO3)2 with nitric acid (HNO3) in the presence of Thiocyanic acid (HSCN) Lead(II) thiocyanate may be made by reacting lead(II) acetate (Pb(CH3COO)2) solved in water with either potassium thiocyanate (KSCN) or ammonium thiocyanate (NH4SCN), thus causing a white precipitation of solid lead(II) thiocyanate.
