What is the chemical formula for polyphosphoric acid?

Synthesis and composition. The basic compounds for the production of polyphosphoric acid (PPA) are phosphorus pentoxide (P2O5) and phosphoric acid (H3PO4), as shown in Figure 2. Phosphorus is first oxidized to phosphorus pentoxide, which crystallizes as P4O10.See all results for this questionWhat are the physical properties of phosphoric acid?Physical properties: Pure phosphoric acid is a white crystalline solid with melting point of 42.35° C. When it is less concentrated, it is a colorless, odorless, viscous liquid with a density of 1.885 g/mL. It is non-toxic and non-volatile. The most common phosphoric acid concentration is 85% in water.See all results for this questionWhat are the hazards of polyphosphoric acid?Hazards. POLYPHOSPHORIC ACID reacts exothermically with chemical bases (examples: amines, amides, inorganic hydroxides). The reactions can generate large amounts of heat in small spaces. Reacts with or corrodes active metals, including such structural metals as aluminum and iron, to release hydrogen, a flammable gas.See all results for this question
