Food grade hydrogen peroxide is safe to be used on food products in minimal amounts. To cook in water that begins cold and then reaches a boil. Edited by G. Brauer, Academic Press, 1963, NY. Sodium peroxide was used to bleach wood pulp for the production of paper and textiles. Sodium peroxide may go by the commercial names of Solozone[7] and Flocool. a yellowish-white, hygroscopic, water-soluble powder, Na, a yellowish-white odourless soluble powder formed when sodium reacts with an excess of oxygen: used as an oxidizing agent in chemical preparations, a bleaching agent, an antiseptic, and in removing carbon dioxide from air in submarines, etc. Which Came First: Turkey The Bird, Or Turkey The Nation?

To cook in water, just below boiling temperature. While the inexpensive liquid is known for its medical uses and bleaching hair, it's also a versatile substance that can be used in a host of other ways.. Hydrogen peroxide (formula H2O2) is a chemical compound that's a combination of hydrogen and water. Vol. [7] With further heating above the 657 °C boiling point, the compound decomposes to Na2O, releasing O2. The iodine can be sublimed by mild heating. 8H2O. Presently it is mainly used for specialized laboratory operations, e.g., the extraction of minerals from various ores. Even if you can't be a professional chef, you can at least talk like one with this vocabulary quiz. Conversely, it may be used to treat the condition when diluted with water or baking soda. “Stuffing” vs. “Dressing”: Do You Know The Difference? Copyright © 2002, 2001, 1995 by Houghton Mifflin Company. Lithium peroxide has similar uses. [5], Sodium peroxide can be prepared on a large scale by the reaction of metallic sodium with oxygen at 130–200 °C, a process that generates sodium oxide, which in a separate stage absorbs oxygen:[7][9]. Describe 2020 In Just One Word? [8], The octahydrate is produced by treating sodium hydroxide with hydrogen peroxide. It is also used in the preparation of sodium peroxide, sodamide and sodium hydride, that have varied industrial applications. [4] The octahydrate, which is simple to prepare, is white, in contrast to the anhydrous material. We Asked, You Answered. 1. p. 979. http://www.nmsu.edu/safety/programs/chem_safety/NFPA-ratingS-Z.htm, https://en.wikipedia.org/w/index.php?title=Sodium_peroxide&oldid=978467206, Articles with changed ChemSpider identifier, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Creative Commons Attribution-ShareAlike License, This page was last edited on 15 September 2020, at 03:04. Except where otherwise noted, data are given for materials in their. Chlorine bleach is produced by combining chlorine and sodium hydroxide. Sodium hydroxide is used to manufacture soaps and a variety of detergents used in homes and commercial applications. “Affect” vs. “Effect”: Use The Correct Word Every Time, The Popular Story About Black Friday’s Name Is A Myth. Egyptians have been using sodium to extensively manufacture glass since 1370 BC. Hydrogen peroxide is a household chemical that can be safely used for a variety of cleaning purposes in your home.

Regular undiluted rinsing with hydrogen peroxide or overuse of mouthwashes containing sodium perborate, sodium peroxide, or hydrogen peroxide is directly associated with the development of BHT. [8] In chemistry preparations, sodium peroxide is used as an oxidizing agent. It is also used as an oxygen source by reacting it with carbon dioxide to produce oxygen and sodium carbonate: It is thus particularly useful in scuba gear, submarines, etc. [6] Upon heating, the hexagonal form undergoes a transition into a phase of unknown symmetry at 512 °C. The octahydrate, which is simple to prepare, is white, in contrast to the anhydrous material. Formula: Na. Drain cleaners that contain sodium hydroxide convert fats and grease that can clog pipes into soap , which dissolves in water. The American Heritage® Stedman's Medical Dictionary E. Dönges "Lithium and Sodium Peroxides" in Handbook of Preparative Inorganic Chemistry, 2nd Ed. A yellowish-white powder used as a germicide, an antiseptic, and a disinfectant. See more. Sodium peroxide definition, a yellowish-white, hygroscopic, water-soluble powder, Na2O2, used chiefly as a bleaching agent and as an oxidizing agent. It may also be produced by passing ozone gas over solid sodium iodide inside a platinum or palladium tube. 8H2O. What Is The Difference Between “It’s” And “Its”? [5], Sodium peroxide crystallizes with hexagonal symmetry. Sodium peroxide hydrolyzes to give sodium hydroxide and hydrogen peroxide according to the reaction[9]. Published by Houghton Mifflin Company. The platinum or palladium catalyzes the reaction and is not attacked by the sodium peroxide. Reacts exothermically and rapidly or even explosively with water to form a strong base (NaOH) and oxygen (O2) [Handling Chemicals Safely 1980 p. 854]. SODIUM PEROXIDE reacts violently with reducing agents, combustible materials and light metals. The ozone oxidizes the sodium to form sodium peroxide. © William Collins Sons & Co.
