Barium thiocyanate is a colorless water-soluble salt that is very hygroscopic. It is highly toxic to ingestion and irritates the skin. It is also soluble in most alcohols and insoluble in simple alkanes.

Uses[edit]

Barium thiocyanate is used in dyeing textiles and is an ingredient in some photographic solutions. But because of its toxicity, it has limited uses.^[3]

Preparation[edit]

Barium thiocyanate is prepared by dissolving barium metal or barium nitrate in a solution of thiocyanic acid.
