This happens due to the formation of a colourless solution of zinc sulphate .you will also observe that during this reaction red-brown copper metal deposits on the piece of zinc. • Metals are also good reducing agents. Zinc metal burns in air only on strong heating to form zinc oxide. 3. The density of metals is usually high. For example, sodium metal is always kept immersed in kerosene oil. In this reaction zinc is more reactive metal than copper present in a copper sulphate solution. For example, 4K + O 2 → 2 K 2 O Metal oxides are generally basic in nature but it can also be amphoteric in nature. The metals and non-metals differ in their properties… November 25, 2020 Nonmetal oxides are known as acidic oxides because they dissolve in water … Metal oxides are generally basic in nature but it can also be amphoteric in nature. By varying the proportion of the chemical composition the desired properties may be imparted. Mg + HCl → MgCl2 + H2 Generally, metals are in a solid state at room temperature. Fe + H2SO4 → FeSO4 + H2. (Sodium oxide + Water → Sodium hydroxide), (Potassium oxide + Water → Potassium hydroxide). When a metal reacts with a dilute acid then a metal salt and hydrogen gas are formed. Metals react with acids and get eroded slowly. For e.g. Iron. 5. some metal oxides are able to dissolve in water to form metal hydroxides (, Reactivity Series or Activity Series of Metals, Enrichment of Ore or Concentration of Ore, Conversion of Concentrated Ore into Metal Oxide, Methods to Obtain Metals of Very High Purity, Experiment to prove that both air and water are necessary for rusting of iron. Non-Metals Almost all metals react with oxygen to form metal oxides. 7.

For example: Sodium, magnesium and zinc reacts with dilute hydrochloric acid to form their salts and hydrogen gas. Form oxides that are acidic. But some metal oxides are able to dissolve in water to form metal hydroxides (or alkali). In the same way sulphur reacts with oxygen of air to form acidic sulphur dioxide. They are very good conductors of electricity and heat. Test your understanding and answer these questions: sodium metal is always kept immersed in kerosene oil. These oxides are alkaline in nature and have high pH above 7 when dissolved in water. Metals react with oxygen to form metal oxides. Some metals like sodium and potassium react vigorously with oxygen. Metallic oxides: Metals can form oxides. • Metals lose electrons easily. Mercury and gallium are metals but they are in liquid state at room temperature. Leadis an exception. General Chemical Properties  Metals when burned in the presence of oxygen, they combine with oxygen to form metallic oxides which are basic in nature. 2Zn      +      O2      →      2ZnO (Zinc + Oxygen → Zinc oxide). Metals react with water to produce metal oxide (or metal hydroxide) and hydrogen gas. Some metals react with air and corrode. Metals also generally have certain distinguishing physical properties that make them easy to identify and classify. Following are the important chemical reactions of metals which takes place due to the electropositive character of metals. 2Na  +  H2   →  2NaH (Sodium + Hydrogen → Sodium hydrides), Ca  +  H2  →   CaH2 (Calcium + Hydrogen → Calcium hydrides). Reaction Of Metal With Oxygen. They are usually in the form of a solid at room temperature. Amphoteric oxides mean that they are acidic as well as basic in nature. Metals donate electrons to oxygen for the formation of metal oxides. For example: Sodium, potassium and calcium metal can react with cold water to produce their hydroxides and hydrogen gas. For example, oxides of sodium and potassium dissolve in water to form sodium hydroxide and potassium hydroxide respectively. More reactive metal displaces the less reactive metal from its oxides, chlorides or sulphides. 4Na      +      O2      →      2Na2O(Sodium + Oxygen → Sodium oxide). Form oxides that are basic. Sodium metal reacts with oxygen of air at room temperature to form basic sodium oxide. (Iron + Copper sulphate(Blue solution) → Iron sulphate(Greenish sol) + Copper(red-brown)). While magnesium, zinc, iron, tin and lead does not react vigorously with acids. Chemical Property of Non Metals: Usually have 4-8 electrons in their outer shell. However, in this article, we will be dealing with the topic of metals and their properties and further understand why some elements are classified into such category. Actually, in this reaction copper metal is more reactive than silver present in silver nitrate solution. Because, if we keep it open, it reacts so vigorously with oxygen present in air that it catches fire. Reaction of Metals with Salt Solutions. The elements are classified as metals and non-metals based on several chemical and physical properties. Metals like sodium, potassium, lithium and calcium react vigorously with dilute HCl and H2SO4 to form their metal salt and hydrogen. As all the metals have different reactivity so they combine with oxygen at different temparature.
