Is phosphorus oxide an amphoteric oxide?

Answer 1

Whether one considers phosphorous pentoxide an acid depends on what definition of an acid is applied. Under the Bronsted-Lowry definition, acids are compounds that donate protons, a definition phosphoric acid fits but not phosphorous pentoxide. Under the Lewis definition, however, an acid accepts a pair of electrons from a base, in which case phosphorous pentoxide is classified as an acid. Its acidic properties are demonstrated by its reaction with water (neutral) to form phosphoric acid (acidic).

Answer 2

No, phosphorus oxide is not an amphoteric oxide. It is a basic oxide, meaning it reacts with water to form a basic solution. Amphoteric oxides can act as both acidic and basic depending on the conditions.

Answer 3

The oxides of phosphorus are acidic in nature (like many other non metallic oxides) in water they produce acids. P2O5 + 3H2O = 2H3PO4 Phosphoric acid.

Answer 4

No its not, its an acidic oxide :)

Answer 5

All oxides of phosphorus are acidic.
