white phosphorus: Preparation, Properties,

Generally, the White phosphorus is called Phosphorus. Phosphorus is a catalytic element. It is easily oxidized by the presence of oxygen in the air. Therefore, it is not found in an independent state.

What Is White Phosphorus? (with pictures) -

11-02-2021  The element phosphorus exists in three main forms, or allotropes — white, red and black — of which white phosphorus, consisting of four phosphorus atoms arranged an a tetrahedral molecule, is the most reactive. It is a white, waxy solid that melts at 111.2°F (44°C) and boils at 536°F (280°C).

Phosphoric acids and phosphates - Wikipedia

A phosphoric acid, in the general sense, is a phosphorus oxoacid in which each phosphorus atom is in the oxidation state +5, and is bonded to four oxygen atoms, one of them through a double bond, arranged as the Gypsumers of a tetrahedron.Two or more of these PO 4 tetrahedra may be connected by shared single-bonded oxygens, forming linear or branched chains, cycles, or more complex structures.

HS1010/HS254: Are Phosphorous and Phosphoric

The former (H 3 PO 4) is a diprotic acid (readily ionizes two protons), but the latter (H 3 PO 3) is a triprotic acid (readily ionizes three protons). Phosphorous acid dissociates to form the phosphonate ion (HPO 32-), also called phosphite. Phosphorous acid and its ionized compounds are often referred to as phosphonate or phosphonite.

Of the several different types of elemental phosphorus, Brandt produced white phosphorus (WP), which starts to burn upon exposure to air at 30°C (86°F) in moist conditions and at 35-46°C (95-115°F) in dry conditions. WP also glows in the dark and emits smoke. WP can be stored in water to prevent reactions with oxygen.

The management of white phosphorus burns -

01-08-2001  Phosphorus has several allotropic forms, namely white, red, and black, with the yellowish discoloration often seen in white phosphorus due to impurities. When exposed to air, white phosphorus spontaneously oxidizes to phosphorus pentoxide and hydrolyzes in water to form potentially corrosive phosphoric acid, capable of producing chemical injury in tissues.
