Diphosphorus pentoxide, also known as phosphorus (V) oxide or phosphoric anhydride is an oxide used as desiccant and dehydrating compound for organic synthesis. A chemical formula of a compound is a representation of the kind and number of constituent atoms of that compound. This oxide presents 4 known structures. Never pour water on this substance; When it must be dissolved or diluted, always add it to the water slowly, in addition to not putting the diphosphorus pentoxide in contact with combustible substances. The solution in water is a strong acid, reacts violently with bases and is corrosive. The revised Drinking Water Directive aims to protect citizens and the environment from the harmful effects of contaminated drinking water and to improve access to drinking water. Phosphorus pentoxide is a potent dehydrating agent as indicated by the exothermic nature of its hydrolysis: Reacting vigorously with water, it is used as a good drying agent for gases and liquids. Exposed to humidity, it becomes viscous as it incorporates water, and its affinity for it is so great that it is frequently used as a dehydrating agent in chemical reactions, especially in organic synthesis. Phosphorous pentoxide is an inorganic chemical compound, composed of four phosphorus atoms and ten oxygen atoms. Diphosphorous pentoxide in the presence of water reacts with metals to form flammable or poisonous gases (hydrogen or phosphine). Most important chemical property is its avidity for water. It’s worth mentioning that diphosphorus pentoxide is a very powerful dehydrating agent.
