Fosforoksiid

Fosforoksiid is a chemical term that can refer to compounds containing phosphorus and oxygen. The most common and significant compound fitting this description is phosphorus pentoxide, with the chemical formula P₂O₅. Phosphorus pentoxide is a white solid that is highly hygroscopic, meaning it readily absorbs moisture from the air. It is a powerful dehydrating agent and reacts vigorously with water to form phosphoric acid. This reactivity makes it useful in various chemical processes, such as the synthesis of phosphoric acid and as a drying agent. Phosphorus pentoxide is an acidic oxide. In its pure form, it exists as a lattice of discrete P₄O₁₀ molecules, which are tetrahedral structures. It is produced industrially by the combustion of phosphorus in excess air. Other less common phosphorus oxides exist, such as phosphorus trioxide (P₄O₆), but phosphorus pentoxide is the most prevalent and widely discussed under the general term "fosforoksiid".
