How can you dry phosphorus pentoxide?

Answer 1

Phosphorus is used as a drying agent to be used with materials that do not react. It is passed through the reaction at a particular temperature. It is a white crystalline solid and serves as a powerful desiccant.

Answer 2

Phosphorus pentoxide can be dried by heating it gently under vacuum or in a desiccator with a drying agent such as silica gel. Avoid high temperatures as it may lead to decomposition. The drying process should be done in a well-ventilated area due to the acidic nature of phosphorus pentoxide.
