Question

Дайте характеристику оксиду фосфора (v) формула которого p2o5

Answer 1

P2O5 кислотный оксид. Взаимодействует:
1) с водой с образованием кислоты
P2O5+3H2O= 2H3PO4
2) с основным оксидом
P2O5+3Na2O=2Na3PO4
3) с основанием
P2O5+6NaOH= 2Na3PO4+3H2O

Answer 2

Characteristics of Phosphorus(V) Oxide (P2O5)

Phosphorus(V) oxide, with the chemical formula P2O5, is a chemical compound with several important characteristics:

Chemical Formula: The chemical formula of phosphorus(V) oxide is P2O5.

Physical State: Phosphorus(V) oxide exists as a white crystalline solid at room temperature.

Reactivity: It is highly reactive and can react vigorously with water to form phosphoric acid.

Applications: Phosphorus(V) oxide is commonly used in the production of phosphoric acid, which is a key ingredient in fertilizers, detergents, and food products.

Chemical Reactions: Phosphorus(V) oxide can undergo various chemical reactions, such as: - P2O5 + H2O = 2HPO3 - P2O5 + 2H2O = H4P2O7 - P2O5 + 3H2O = 2H3PO4 - P2O5 + 3CaO = Ca3(PO4)2 - P2O5 + 6NaOH = 2Na3PO4 + 3H2O [[6]](https://prosto-o-slognom.ru/chimia/505_oksidy_fosfora.html).
