Reaction of phosphorus with air. White phosphorus glows in the dark when exposed to damp air in a process known as chemiluminescence. White phosphorus must be handled with great care. It spontanteously ignites in air at about room temperature to form "phosphorus pentoxide" - actually tetraphosphorus decaoxide, P 4 O 10. P 4 (s) + 5O 2 (g) → P ...
18.9: The Chemistry of Phosphorus - Chemistry LibreTexts
Phosphorus occurs in at least 10 allotropic forms, the most common (and reactive) of which is so-called white (or yellow) phosphorus, which looks like a waxy solid or plastic. It is very reactive and will spontaneously inflame in air, so it is stored under water.
CHEMICAL REACTIONS OF THE PERIOD 3 ELEMENTS - chemguide
Phosphorus. White phosphorus catches fire spontaneously in air, burning with a white flame and producing clouds of white smoke - a mixture of phosphorus(III) oxide and phosphorus(V) oxide. The proportions of these depend on the amount of oxygen available. In an excess of oxygen, the product will be almost entirely phosphorus(V) oxide.

2024年10月21日 · It is highly toxic, reacts vigorously with most reagents, and inflames in air at only 35° C (95 °F), so it must be stored under water or other inert liquid. White phosphorus dissolves readily in solvents such as carbon disulfide, in which it maintains the composition P 4.

8.9.3: Chemistry of Phosphorus (Z=15) - Chemistry LibreTexts
Phosphorus occurs in at least 10 allotropic forms, the most common (and reactive) of which is so-called white (or yellow) phosphorus, which looks like a waxy solid or plastic. It is very reactive and will spontaneously inflame in air, so it is stored under water.
Active Part of Air: Phosphorus in Air - Chemistry Form 1
Phosphorus smolders easily in air, reacting with oxygen (active part of air) to form phosphorus (III) or phosphorus (V) oxide; For this reason, phosphorus is stored under water; to prevent it from reacting with atmospheric oxygen;
Properties and Reactions of Phosphorus - Definition and
White phosphorus is poisonous and has the maximum number of chemical reactions. It instantly catches fire when it comes in contact with air. Storing white phosphorus with water is the best thing to do to avoid fire or flames.

Phosphorus - Sciencemadness Wiki
2022年10月16日 · White phosphorus reacts with air and can spontaneously ignite, if heated slightly, forming phosphorus pentoxide. Red phosphorus is much more stable in air, but will react with halogens. Phosphorus chlorides, for example, are formed from the reaction of white phosphorus and chlorine gas.
