What is P4O7? Important knowledge about P4O7

1. Definition of P₄O₇

P₄O₇, also known as Tetraphosphorus heptoxide, is also known in English as Phosphorus pentoxide. It is a colorless compound with a molar mass of 141.94 g/mol. P₄O₇ consists of 4 atoms of Phosphorus (P) and 7 atoms of Oxygen (O). In theory, the structure of the P₄O₇ molecule is seen as the bond between P and O atoms forming a conjugated system. However, P₄O₇ does not form ions in solution.
