Barium nitrate, represented by the chemical formula Ba(NO3)2, is an inorganic compound composed of barium, nitrogen, and oxygen. It appears as a white crystalline solid and is highly soluble in water. Barium nitrate is commonly used in pyrotechnics to produce green flames and as a precursor for other barium compounds. In addition to its use in fireworks, Ba(NO3)2 serves various industrial applications, including in the manufacturing of glass and ceramics. It is also utilized in laboratories for chemical synthesis and as a reagent. However, care must be taken when handling barium compounds, as they can be toxic if ingested.
