white phosphorus

(i) It is a soft waxy solid with garlic smell. (ii) It is poisonous in nature. (iii) It turns yellowish on exposure to light. For this reason, it is also called yellow phosphorus. (iv) It is not soluble in water but soluble in carbon disulphide. (v) It undergoes spontaneous combustion in..

Elemental phosphorus is obtained by heating phosphate rock with coke and silica in an electric furnace at about 1770 K. The phosphorus so formed is white phosphorus . The reaction may be represented a..

Take a small piece of yellow phosphorus in a deflagrating spoon and introduce it into a jar of oxygen. It will start smouldering and give off white fumes of phosphorus (V) oxide. Take another yellow phosphorus piece and heat it gently till it catches fire; n..

It is prepared by heating white phosphorus to about 470 K under high pressure of 1200 atmospheres in inert atmosphere. (i) It has metallic lustre. (ii) It is most inactive form of phosphorus. (iii) It has a layer type structure in which each layer consists..

Yellow phosphorus first melts and then catches fire spontaneously when introduced into a jar of chlorine gas. It forms thick white fumes of phosphorus (III) chloride and phosphorus (V) chloride (Fig.14.9). ..

. Re-adjust the coin if necessary. Take a long thin metal rod, heat one end of it and introduce it into the bell jar. Just touch the phosphorus with the hot end and withdraw it immediately. Then cover the bell jar tightly with the lid. You will notice that the yellow phosphorus ..

2 and MO type oxides. Their chemistry is characterized by (+2) oxidation state. In general, the heavier p-block elements favor low oxidation states. The most important element of group 15 is phosphorus. It exists in white, red and black allotropic forms. It forms molecular ..

On hydration, quick lime forms slaked lime or lime water. When water is added to lime it becomes hot and cracks to form a white powder. This is called slaking of lime. Calcium oxide is a basic oxide. It can react with acids to give calcium salts. With acidic oxides like silicon ..
