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
Potassium chlorate conclave. Potassium chlorate is often used in high school and college laboratories to generate oxygen gas. It is a far cheaper source than a pressurized or cryogenic oxygen tank. Potassium chlorate readily decomposes if heated while in contact with a catalyst, typically manganese(IV) dioxide (MnO). Thus, it may be simply placed in a test tube and heated over a burner. If the test tube is equipped with a one-holed stopper and hose, warm oxygen can be drawn off. The reaction is as follows: Heating it in the absence of a catalyst converts it into potassium perchlorate: With further heating, potassium
