Barium peroxide Barium peroxide Barium peroxide is the inorganic compound with the formula BaO. This white solid (gray when impure) is one of the most common inorganic peroxides, and it was the first peroxide compound discovered. Being an oxidizer and giving a vivid green colour upon ignition (as do all barium compounds), it finds some use in fireworks; historically, it was also used as a precursor for hydrogen peroxide. Barium peroxide is a peroxide, containing subunits. The solid is isomorphous to calcium carbide, CaC. Barium peroxide arises by the reversible reaction of O with barium oxide. The peroxide forms around 500 °C
Barium acetate the words "barium acetate" in hopes of preventing future "copycat" crimes. The print media, and a 2014 episode of the crime documentary series "Redrum", have not been so circumspect. Also named as the choice poison of a teen's murder of her father in Deadly Women "Parents Peril", S6 E2. Barium acetate Barium acetate (Ba(CHO)) is the salt of barium(II) and acetic acid. Barium acetate is generally produced by the reaction of acetic acid with barium carbonate: The reaction is performed in solution and the barium acetate crystallizes out. Alternatively, barium sulfide can be used: Again, the solvent is evaporated off
