Phosphate is the conjugate base of phosphoric acid, which is produced on a massive scale for use in fertilisers. A wide variety of White phosphorus options are available to you. … It is hard and crystalline solid. Red phosphorus is a purple or slightly brown amorphous powder that is shiny. It can be viewed as a derivative of P 4 — one of the P-P bonds is broken, and one additional bond is formed between the neighboring tetrahedrons, resulting in a chain-like structure. Phosphorus occurs in both organic and inor-when P 4 is exposed to air. We can store this compound underwater because it is slightly soluble in water. It can only safely be kept under water. This structure causes its ring strain and instability. All rights reserved. Formula: P. CAS Number: 7723-14-0. Or maybe you remember its atomic symbol of P. Something else well known about phosphorus is that it exists in other forms, or allotropes. The former is a waxy, yellowish-white, very inflammable, and poisonous solid. Join now. It is non poisonous. Structure. It is hard and crystalline solid. White phosphorus is a waxy white solid. Elementary phosphorus exists in three principal allotropic forms, i.e. Red. The substance known as yellow phosphorus is actually white phosphorus that contains impurities (e.g., red phosphorus) or that has darkened from exposure to light. Perhaps you think about the fact that its atomic number is 15 on the periodic table. Atoms are represented as spheres: carbon (grey), hydrogen (white), nitrogen (blue), oxygen (red), phosphorus (orange). Red phosphorus is an odorless allotropic form and is certainly more stable than white phosphorus. Product Details: Name: Red Phosphorus. It does not show phosphorescence. a. variable. That is, heating the white phosphorous up to 300 °C makes this conversion between two allotropic forms. When pure, it is colourless.

White phosphorus would ignite at about 40o C while the red version only catches fire in the air at temperatures above 240o C. In pyrotechnics, phosphorus is used in compositions that ignite through friction and in mixtures that burn very brightly, such as Armstrong's mixture. Similarly, dermal application of the element to guinea pigs resulted in no skin irritation or sensitization. It is insoluble in water, but soluble in carbon disulfide, an organic solvent. Structure of the black form of this substance is shown below: Since it can form three bonds, phosphorus can form a P4 white phosphorus tetrahedron, while sulphur can only form two bonds. Phosphorus, White. Hence, sulphur only forms rings and chains. It is less reactive: It is soft waxy solid and can be easily cut with a knife. Let us discuss more details on the difference between red and white phosphorus. No dermal irritation was noted when red phosphorus was applied to the skin of rabbits at doses of 0.5 g per site. Further, this compound has a polymeric structure. It is highly toxic. P 4, its molecular weight is 124 amu. Phosphorus molecules of formula P 2, structurally analogous to N 2 molecules and evidently also triply bonded, exist only at very high temperatures. This produces phosphorus as a vapour, which is then collected under water. The substance known as yellow phosphorus is actually white phosphorus that contains impurities (e.g., red phosphorus) or that has darkened from exposure to light. Phosphorus: Phosphorus forms several simple substances, the most widely distributed are white phosphorus, consisting of P 4 molecules, and red phosphorus, which has a crystal atomic lattice. White P is soluble in carbon di sulfide and small amount in water, but red P is not soluble in both water and carbon disulfide Moreover, it is chemically active. Phosphorus is essential for life.

Elemental phosphorus exists in two types - white phosphorus and red phosphorus It consists of white phosphorus with sun light and heat effect. Red Phosphorus. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). Importantly, it appears as dark red colored crystals. The least stable, the most reactive, the most volatile, the least dense, and the most toxic of the allotropes is white phosphorus. It is more stable than white phosphorus. In addition to that, it ignites in air at low temperatures such as 50 °C. This evolves elemental phosphorus.
