Barium nitrate inhalation, it can still result in irritation, itching, redness, and pain. The Occupational Safety and Health Administration and the National Institute for Occupational Safety and Health have set occupational exposure limits at 0.5 mg/m over an eight-hour time-weighted average. Barium nitrate Barium nitrate is the inorganic compound with the chemical formula Ba(NO). It, like most barium salts, is colorless, toxic, and water-soluble. It burns with a green flame and is an oxidizer; the compound is commonly used in pyrotechnics. Barium nitrate is manufactured by two processes that start with the main source material for barium, the carbonate. The first involves
Chlorate were once widely used in pyrotechnics for this reason, though their use has fallen due to their instability. Most pyrotechnic applications that formerly used chlorates now use the more stable perchlorates instead. The chlorate ion cannot be satisfactorily represented by just one Lewis structure, since all the Cl–O bonds are the same length (1.49 Å in potassium chlorate), and the chlorine atom is hypervalent. Instead, it is often thought of as a hybrid of multiple resonance structures: Metal chlorates can be prepared by adding chlorine to hot metal hydroxides like KOH: In this reaction, chlorine undergoes disproportionation, both reduction and
