Barium can form two distinct compounds with oxygen as the only other element in the compound: barium oxide with formula BaO and barium peroxide with formula BaO2. For other uses, see, Except where otherwise noted, data are given for materials in their, S.C. Middleburgh, K.P.D. It can cause nausea and diarrhea, muscle paralysis, cardiac arrhythmia, and can cause death. [4], The reaction was used as a large scale method to produce oxygen before the air separation became the dominant method in the beginning of the 20th century. Being an oxidizer and giving a vivid green colour upon ignition, it finds some use in fireworks; historically, it was also used as a precursor for hydrogen peroxide. BaO. Its molar mass is 153.33 g/mol. It is prepared by heating barium carbonate with coke, carbon black or tar or by thermal decomposition of barium nitrate. One ion of barium neutralizes one ion of oxygen, hence those two ions combine to form barium oxide, BaO. Continue Reading.

It readily oxidises to BaO2 by formation of a peroxide ion. The complete peroxidation of BaO to BaO2 occurs at moderate temperatures but the increased entropy of the O2 molecule at high temperatures means that BaO2 decomposes to O2 and BaO at 1175K. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Barium oxide | BaO | CID 62392 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, … 30 terms. It replaced lead(II) oxide in the production of certain kinds of glass such as optical crown glass. Naming Ionic Compounds with Polyatomic Ions. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Likewise, it is often formed through the decomposition of other barium salts. It is harmful to human skin and if swallowed in large quantity causes irritation. Barium oxide. The method was named after its inventors the Brin process. Barium oxide should not be released environmentally; it is harmful to aquatic organisms. It replaced lead (II) oxide in the production of certain kinds of glass such as optical crown glass. This white solid is one of the most common inorganic peroxides, and it was the first peroxide compound discovered. 1304-28-5 Barium oxide (100.0%) PEL (USA) Long-term value: 0.5 mg/m 3 as Ba REL (USA) Long-term value: 0.5 mg/m 3 as Ba TLV (USA) Long-term value: 0.5 mg/m 3 as Ba EL (Canada) Long-term value: 0.5 mg/m 3 as Ba Additional information: No data Exposure controls Personal protective equipment Follow typical protective and hygienic practices for handling chemicals. The structural depiction of Barium Oxide is as shown in the figure below. They have the same structure as sodium chloride, with each atom having six neighbours. It readily oxidises to BaO_1+x_ by formation of a peroxide ion. Another way to prevent getting this page in the future is to use Privacy Pass. Likewise, it is often formed through the decomposition of other barium salts. OTHER SETS BY THIS CREATOR. [3], It is also a source of pure oxygen through heat fluctuation. In crystal: Ionic bonds …ionic binary crystals such as barium oxide (BaO), calcium sulfide (CaS), barium selenide (BaSe), or strontium oxide (SrO). [6] Likewise, it is often formed through the decomposition of other barium salts.[7]. It has a cubic structure and is used in cathode ray tubes, crown glass, and catalysts. • So Barium on getting oxidized forms the ionic compound is BaO ( Barium Oxide ) Ba^(2+) + O^(2-) rarr BaO Periodic Table Glossary of Terms. Linear Formula: BaO. Synonym: Baria, Barium monoxide. Barium Oxide Structural Formula. Oxygen can be combined with various cations to form a large number of ionically bonded solids. BaO + H 2 O → Ba (OH) 2. 31 terms. Mercury(II) oxide …
