Today we often use chemical formulas, such as NaCl, C 12 H 22 O 11, and Co(NH 3) 6 (ClO 4). Examples of compounds for which common names are used include water. Compounds of oxygen - Wikipedia. Water (H2. O) is the most familiar oxygen compound. The oxidation state of oxygen is . Common Names of Some Chemical Compounds. ![]() ![]() COBALT AND COBALT COMPOUNDS (Group 2B) For definition of Groups, see Preamble Evaluation. Cobalt compounds have been used as pigments in glass and ceramics in many countries for thousands of years. Common Oxoacid Compounds Table of Common Oxoacids Share Pin Email Acetic acid is a. H 2 CO 3: carbonate: CO 3 2-chloric acid: HClO 3: chlorate: ClO 3 = chlorous acid: HClO 2: chlorite: ClO 2-hypochlorous acid: HClO. ![]() Compounds containing oxygen in other oxidation states are very uncommon: . Its bulk properties partly result from the interaction of its component atoms, oxygen and hydrogen, with atoms of nearby water molecules. Hydrogen atoms are covalently bonded to oxygen in a water molecule but also have an additional attraction (about 2. J. However, some elements, such as iron which oxidises to iron oxide, or rust, Fe. O3, readily oxidise at standard conditions for temperature and pressure (STP). The surface of metals like aluminium and titanium are oxidized in the presence of air and become coated with a thin film of oxide that passivates the metal and slows further corrosion. As a result, none of these elements is found in nature as a free metal. Caesium is so reactive with oxygen that it is used as a getter in vacuum tubes. Although solid magnesium reacts slowly with oxygen at STP, it is capable of burning in air, generating very high temperatures, and its metal powder may form explosive mixtures with air. Oxygen is present as compounds in the atmosphere in trace quantities in the form of carbon dioxide (CO2) and oxides of nitrogen (NOx). The earth's crustalrock is composed in large part of oxides of silicon (silica. Si. O2, found in granite and sand), aluminium (aluminium oxide. Al. 2O3, in bauxite and corundum), iron (iron (III) oxide. Fe. 2O3, in hematite and rust) and other oxides of metals. 6 Cobalt in Chemicals Cobalt. Cobalt Compounds in Pigments Colour Compounds. Other inorganic compounds. Water- soluble silicates in the form of Na. Si. O4, Na. 2Si. O3, and Na. Si. 2O5 are used as detergents and adhesives. White or light yellow sodium peroxide (Na. O2) is formed when metallic sodium is burned in oxygen. Each oxygen atom in its peroxide ion may have a full octet of 4 pairs of electrons. For example, potassium superoxide (KO2) is an orange- yellow solid formed when potassium reacts with oxygen. Hydrogen peroxide (H2. O2) can be produced by passing a volume of 9. For example, sodium oxide in solution forms the strong base sodium hydroxide, while phosphorus pentoxide in solution forms phosphoric acid. Oxygen forms heteropoly acids and polyoxometalate ions with tungsten, molybdenum and some other transition metals, such as phosphotungstic acid (H3. PW1. 2O4. 0) and octadecamolybdophosphoric acid (H6. P2. Mo. 18. O6. 2). One unexpected oxygen compound is dioxygenyl hexafluoroplatinate, O+2. Pt. F. The cations of oxygen are formed only in the presence of stronger oxidants than oxygen, which limits them to the action of fluorine and certain fluorine compounds. Simple oxygen fluorides are known. There are many important organic solvents that contain oxygen, among which: acetone, methanol, ethanol, isopropanol, furan, THF, diethyl ether, dioxane, ethylacetate, DMF, DMSO, acetic acid, formic acid. Acetone ((CH3)2. CO) and phenol (C6. H5. OH) are used as feeder materials in the synthesis of many different substances. Other important organic compounds that contain oxygen are: glycerol, formaldehyde, glutaraldehyde, citric acid, acetic anhydride, acetamide, etc. Epoxides are ethers in which the oxygen atom is part of a ring of three atoms. Oxygen reacts spontaneously with many organic compounds at or below room temperature in a process called autoxidation. Most of the organic compounds that contain oxygen are not made by direct action of oxygen. Organic compounds important in industry and commerce are made by direct oxidation of a precursor include. Only a few common complex biomolecules, such as squalene and the carotenes, contain no oxygen. Of the organic compounds with biological relevance, carbohydrates contain the largest proportion by mass of oxygen (about 5. All fats, fatty acids, amino acids, and proteins contain oxygen (due to the presence of carbonyl groups in these acids and their ester residues). Furthermore, seven of the amino acids which are incorporated into proteins, have oxygen incorporated into their side- chains, as well. Oxygen also occurs in phosphate (PO4. Accessed January 2. Chaplin, Martin (2. The interactions between the different dipoles of each molecule cause a net attraction force.^The aluminium oxide layer can be built to greater thickness by the process of electrolyticanodizing.^ abcd.
