(b) Non-metals cannot lose electrons so that H + ions from acids become hydrogen gas and can be displaced. Some metals do not react at all with water for example copper; When metals do react with water they bond with oxygen; And displace hydrogen gas \text{metal + water}\rightarrow\text{metal oxide+hydrogen} The hydrogen can be tested by bringing a burning splint near the mouth of the test tube; Compounds so formed are known as Ionic Compounds. They react vigorously, and often violently, with water to release hydrogen and form strong caustic solutions. 3) Reaction of non metal with acid : non-metals do not react with acids. (AI 2008) Answer: (a) The oxides which are acidic as well as basic in nature are called amphoteric oxides. Non-metals are themselves acceptors of electrons so there is no way they can donate electrons to the hydrogen ion of the acid.

What your notebook says is a simplified general statement, it is not universally true but it is true of most non-metals, ie that they cannot break the H-O bond in water, in particular they cannot do so to form oxides or hydroxides in the way that metals can. Explore how alkali metals react with water using a series of demonstrations and videos in this lesson plan with activities for 14–16 year olds. 5 years ago. 4. Hence, non-metals in general do not react with acids. But there are exceptions also like phosphorus,carbon etc. Metals reacting with water form metal oxides. Basic solution turns red litmus into blue. Let us check by performing the following Activity. In each reaction, hydrogen gas is given off and the metal hydroxide is produced. The reactions of carbon and sulfur with oxygen are examples of non-metals reacting with oxygen. Source(s): alkali metals react violently water: https://shortly.im/lU1K0. 8. (a) FeO (b) Fe 2 O 3 (c) Fe 3 O 4 Al 2 O 3 and ZnO are amphoteric oxides. (a) Na (b) Ca (c) Mg (d) Fe Metals and Non-metals CHAPTER3 5. For example:-Carbon react with sulphuric acid producing CO2,SO2 and water. The non-metal and oxygen gas (O 2) are the reactants in this type of reaction, and a non-metal oxide is the product. In the case of non metal they show higher concentration of H ion. Reaction of Non-metals with Dilute Acids. ... Na, Ca and Mg are reactive metals and quickly react with water. Sodium and potassium do not react vigorously with water and oxygen. 4. Non-metals react with oxygen to form non-metal oxides. So, they do not displace hydrogen from dilute acids. Metals react with water to form oxides or hydroxides and release Hydrogen gas. For the best answers, search on this site https://shorturl.im/avveM. At room temperature, the reaction of Fe is very slow but red hot iron reacts with steam to form Fe 3 O 4 with hydrogen gas. Na + H 2 O ⇨ NaOH + H 2 At a time, it shows only five questions per set of MCQ test. The alkali metals such as sodium, potassium and lithium react with water to produce heat and flammable hydrogen gas, which can ignite or combine explosively with atmospheric oxygen. Reactions of alkali metals with water All the alkali metals react vigorously with cold water. Metals and non-metals can also be distinguished by some chemical properties.
