Phosphorus pentoxide $(P_{2} O_{5})$ is a white solid. It forms an acidic solution with water.
$P_{2} O_{5} + 3 H_{2} O \to orthophosphoric acid 2 H_{3} P O_{4}$

Phosphorus pentoxide (P2​O5​) is a white solid. It forms an acidic solution with water. P2​O5​+3H2​O→ orthophosphoric acid 2H3​PO4​​

Phosphorus pentoxide $(P_{2} O_{5})$ is a white solid. It forms an acidic solution with water.
$P_{2} O_{5} + 3 H_{2} O \to orthophosphoric acid 2 H_{3} P O_{4}$
