Barium Chloride Dihydrate

Barium chloride dihydrate is a chemical compound with the molecular formula BaCl2·2H2O. It is a white crystalline solid that is highly soluble in water. At room temperature, it exists as a monoclinic crystal structure with the space group P21/c.

Barium chloride dihydrate is commonly used in laboratory settings as a reagent for various chemical reactions. It can also be used in the manufacture of other chemicals, such as barium chromate and barium fluoride.

One important consideration when handling barium chloride dihydrate is its toxicity. It is classified as a hazardous substance and exposure to it can cause irritation to the skin and eyes, as well as respiratory issues if inhaled. It should be handled with appropriate safety precautions, including wearing protective clothing, gloves, and eyewear.

In terms of its properties, barium chloride dihydrate has a molar mass of 244.26 g/mol and a density of 3.10 g/cm3. Its melting point is 963 °C, and it decomposes at higher temperatures to form barium oxide and hydrochloric acid. It has a high affinity for water and will readily absorb moisture from the surrounding air.

Overall, barium chloride dihydrate is an important industrial chemical that requires careful handling due to its toxicity. Its properties make it useful in various applications, particularly in laboratory settings where it is used as a reagent.
