Water itself is also a neutral oxide. Thus, acidic oxide on reacting with water gives base. Metal oxides are formed as a consequence of co-ordination tendency of metal ions so that oxide ions form co-ordination sphere around metal ions and give rise to close packed structure. However, they react with alkalis to form salt and water. An example of acidic oxide is sulphur trioxide SO3. The oxides of transition metals such as Nb2 O 5 ( Tagusagawa et al., 2010 ), WO 3 ( Tagusagawa et al., 2010 ), and TiO 2 ( Kondo et al., 2005) are widely used as heterogeneous acid nanocatalysts. These two simple oxides can be of the same metal (element) or different. ) Each disc includes powdered zinc oxide material mixed with other metal oxides. The IUPAC also accepts the stoichiometric nomenclature for these oxides, though it is better to use the Stock´s nomenclature when there are metallic atoms and the stoichiometric nomenclature when all the atoms are nonmetals. The synthesis of various two-dimensional transition metal oxides and the demonstration of high capacitance are expected to enable fundamental studies of dimensionality effects on their properties and facilitate their use in energy storage and other applications. Zinc(II) Oxide. There are three types of metal oxides formed alkali metals and alkaline earth metals. When sulfur trioxide reacts with water, it forms sulfuric acid. An oxide is a chemical compound that contains at least one oxygen atom and one other element. An oxide film is normally a thin layer deposited on the surface of a metal which has undergone an oxidation reaction from air or moisture surrounding the material. When we burn magnesium ribbon it reacts with atmospheric oxygen and forms a grey colored compound which is magnesium oxide. There is a trend within acid-base behavior: basic oxides are present on the left side of the period and acidic oxides are found on the right side. In this article we will discuss all four types of oxides with examples and uses however before that we are explaining what oxides are, in brief here. Some examples are carbon monoxide and nitric oxide. Most acidic oxides dissolve in water to form an acid. For example, zinc oxide acts as an acidic oxide when it reacts with concentrated sodium hydroxide. These are termed as oxides because here, oxygen is … Introduction c-Type cytochromes (c-Cyts) are ubiquitous in nearly all living organisms, where they play vital roles in mediat-ing electron transfer (ET) reactions associated with respiration. The reaction depends on the element, the acidity of the metal oxide and on the physical state of the water.
