Barium cyanide is a chemical compound with the formula Ba(CN) 2. It is synthesized by the reaction of hydrogen cyanide and barium hydroxide in water or petroleum ether . [ 1 ] It is a white crystalline salt.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Soluble salts such as sodium cyanide (NaCN) and potassium cyanide (KCN) are highly toxic. [2] Hydrocyanic acid , also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially.
Barium thiocyanate refers to salts of the formula Ba(SCN) 2. xH 2 O. Both an anhydrous salt and a trihydrate are known. The anhydrous salt is hygroscopic. The trihydrate is soluble in most alcohols but insoluble in simple alkanes. Barium thiocyanate is used in dyeing textiles and in some photographic solutions. But because of its toxicity, it ...
Barium compounds are added to fireworks to impart a green color. Barium sulfate is used as an insoluble additive to oil well drilling fluid. In a purer form it is used as X-ray radiocontrast agents for imaging the human gastrointestinal tract. Water-soluble barium compounds are poisonous and have been used as rodenticides.
If a green pigment and barium sulfate (for increased transparency) are added it can also serve as a replacement for barium chromate, which possesses a more greenish cast than the others.
Like all soluble barium compounds, barium nitrate is toxic by ingestion or inhalation. [8] Solutions of sulfate salts such as Epsom salts or sodium sulfate may be given as first aid for barium poisoning, as they precipitate the barium as the insoluble (and non-toxic) barium sulfate. Inhalation may also cause irritation to the respiratory tract.
