Barium Thiocyanate

Barium thiocyanate is a white crystalline solid with the chemical formula Ba(SCN)2, which consists of one barium ion (Ba2+) and two thiocyanate ions (SCN^-) bonded together. It has a molecular weight of 365.51 g/mol.

Barium thiocyanate is soluble in water, ethanol, and acetone. It is commonly used as a reagent in analytical chemistry to detect the presence of iron(III) ions, which react with the thiocyanate ions to form a blood-red colored complex.

In addition, barium thiocyanate has been used in the production of photographic paper as a component of the light-sensitive layer. When exposed to light, it forms an insoluble complex that helps to create an image on the paper.

Barium thiocyanate is also used in the manufacturing of pigments, dyes, and other chemicals. However, it should be handled with care as it is toxic if ingested or inhaled, and can cause skin and eye irritation upon contact. Appropriate protective measures, such as gloves and goggles, should be worn when handling this substance.
