phosphorus pentoxide

Extreme drying agent

Phosphorus pentoxide is a white crystalline compound (P₂O₅) that reacts violently with water, making it one of the most powerful drying agents known.

It absorbs moisture so aggressively that it's used in laboratories to create extremely dry conditions: The sample was stored over phosphorus pentoxide to remove all traces of water.
