NCERT Solutions for Class 10 Science Chapter 3 Metals and Non-metals. Enrichment or dressing of an ore is carried out by the following methods. Titanium tetra-iodide gets decomposed into titanium and iodine. A solution of the salt of the metal acts as the electrolyte. This vessel is called cupel. Electromagnetic induction. The regenerated iodine can be reused to react with more titanium. The main article for this category is Metallurgical processes . Free Online BASIC METALLURGICAL PROCESSES Practice & Preparation Tests. Extraction of metal from the metal oxide 4. Ohm's law 3. 2Al(OH)  →  Al2O3 + 3H2O Conversion of the enriched ore into the oxide of metal, Conversion of the enriched ore into the oxide of metal. Downloads for CBSE Class 10 Science. Copper is purified by this method. The impure metal is made the anode while a strip of pure metal acts as the cathode. These downloads are arranged subject-wise and topic-wise.

Simply apply as teacher, take eligibility test and start working with us. TEEL MAKING. This consists of 1 mark Questions, 3 Mark Numericals Questions, 5 Marks Numerical Questions and previous year questions from Metals and Non-Metals Chapter. font-size: 14px; The precipitate, when filtered, washed, dried and ignited, gives pure alumina (A12O3). In this process the ore is heated very strongly in the absence of air, keeping the temperature below its melting point so that volatile impurities are driven off. Extractive Metallurgy: Techniques used to win metals from mineral ores, including hydrometallurgical, pyrometallurgical, and electrometallurgical techniques. (ii) Carbonate ores are calcined to expel carbon dioxide. Lead is oxidized to lead monoxide. 10,000+ Fundamental concepts. 1. Download NCERT Textbook (PDF) for CBSE Class 10 Science Human Eye and Colourful World (Deleted Human Eye Part) Power of a lens; Functioning of a lens in human eye, defects of vision and their corrections, applications of spherical mirrors and lenses. S . Extraction of metal from metal oxide : A metal oxide thus produced is then reduced into metal. They can repeat the lessons as many times as required. Titanium metal is heated which reacts with iodine to form gaseous titanium tetra-iodide. When a metal oxide is heated with carbon, it is reduced to free metal. The impure metal is made the anode while a strip of pure metal acts as the cathode. (iii) Electrolytic reduction : The reactive metals (high up in the activity series) cannot be produced by any of the above methods. Give two examples of amphoteric oxides. Metallurgy 1.

Properties of Metals and Non Metals Ionic compounds Basic Metallurgical Processes Corrosion and its prevention. For example, the bauxite ore contains Fe2O3, SiO2, etc., as impurities. Enrichment or dressing of the ore 2. The impurities are removed as slag. Applications 5. MOLTEN IRON. My child is interested in learning only some subjects. Refraction; Laws of refraction, refractive index. What is the Process of Metallurgy The various steps used in metallurgy are listed below. Cu(OH)  →  2CuO + H2O + CO2 Sulphide ores are usually converted to oxides by roasting. Two special techniques have been devised to prepare metals of very very high purity. The gases escaping from the poles reduce the oxide of metal to the metal. (iv) Magnetic separation : This method is used when the magnetic properties of the ore and the impurities are different. In case of iron oxide, iron is obtained in the molten state. (iii)Aluminium oxide (Al2O3) is reduced to aluminium by the electrolysis of molten aluminium oxide. (iii) Cinnabar (HgS) is roasted to convert it directly into mercury (Hg). The impure silver is heated in the presence of air in a vessel made of bone-ash. The gases escaping from the poles reduce the oxide of metal to the metal. (ii) Ferric oxide (FeP3) is reduced by aluminium to free iron. Classes. text-transform: none; The powdered tinstone is spread on a belt moving over electromagnetic rollers in figure. (i)   Manganese dioxide is reduced to manganese by heating with aluminium. ICSE Class 10 Revision Notes. Pure titanium is deposited upon the filament and can be removed. 2. Child bearing and women's health. Enrichment or dressing of the ore 2. The impure metal is placed at the top of the hearth. The main article for this category is Metallurgical processes . Non-metals form acidic oxides, do not react with water and dilute acids to form Hydrogen gas. Renewable versus non-renewable sources of Energy. A12O3 and SiO2 present in the ore dissolve, forming sodium aluminate and sodium silicate respectively. (ii)  When stannic oxide is heated with carbon, tin metal is produced. Pure silver is left behind. window.__mirage2 = {petok:"0051da5125f850ca27fefc18f1219fd3eca4b199-1606768755-1800"}; Basic concept of nutrition,respiration, transport and excretion in plants and animals. 20,000+ Learning videos.
