Why metal like Sodium and Calcium can not be reduced by any reducing agent:


Which of the following step is involved during the process: Roasting


Aluminium is a young material, and in the little more than a century since its first commercial production, it has become the world’s second most used metal after steel. Aluminium is the metal of choice for leading designers, architects and engineers, all of whom are looking for a material which combines functionality and cost-effectiveness with forward looking form and design potential. Which of the following process is involved in refining of Aluminium:


Which of the following is not the ore of Iron:


Which of the following process is invovled for separation of Lead with impurity of silver:


Sodium is an essential element for all animal life (including human) and for some plant species. In animals, sodium ions are used in opposition to potassium ions, to allow the organism to build up an electrostatic charge on cell membranes, and thus allow transmission of nerve impulses when the charge is allowed to dissipate by a moving wave of voltage change. Sodium is thus classified as a "dietary inorganic macro-mineral" for animals. Sodium's relative rarity on land is due to its solubility in water, thus causing it to be leached into bodies of long-standing water by rainfall. Such is its relatively large requirement in animals, in contrast to its relative scarcity in many inland soils, that herbivorous land animals have developed a special taste receptor for the sodium ion.

Why during the metallurgy of Sodium from Sodium Chloride impurites for Calcium Fluoride is added:


The alkali metal are stored in Kerosine or Paraffin as they are highly reactive. Lithium is the only metal which is not stored in Kerosine rather than is wrapped in wax:


Which of the following process invovles for the Carbonate ore:


Which of the following term in metallurgy is related to Impurity:


Which of the following metal is invovled in the development of Photography and Photographic Films


Which of the following statement is true for ore and mineral


Aqua regia (Latin for "royal water") is a highly corrosive, fuming yellow or red

solution. The mixture is formed by freshly mixing _______________ and ______________. And is used to dissolve Gold like noble metal:


Why it is difficult during the metallurgy of Transition and Inner transition element:


Which of the following process is invovled in refining of Copper metal


Copper metal is extracted from molten matte through bessemerization . The matte is introduced in to Bessemer converter which uphold by tuyers. The air is blown through the molten matte. Blast of air converts Cu2S partly into Cu2O which reacts with remaining Cu2S to give molten copper.

2Cu2S + 3O2 è 2Cu2O + 2SO2

2Cu2O + Cu2Sè 6Cu + SO2

The above method of reduction donot invovle any other reducing agent and therefore the process is called as self reduction process. Name the other elements which involve the same process:


Which of the following form of iron is the purest form of Iron
