The transport of orthophosphoric acid (phosphoric acid) includes the delivery of inorganic acids of moderate strength, which are naturally colorless crystals that absorb moisture from the air. Since this acid is easily soluble in liquids (water, ethanol, various solvents), the transportation of phosphoric acid is the delivery of an 85 percent mixture with water, where the mass of orthophosphoric acid exceeds 73 %. Such mixtures of concentrated acids have a strong viscosity and a high density of about 1.69 g / cm3. The salt of orthophosphoric acids is called phosphates. ADR classifies the transport of orthophosphoric acid as the transport of caustic substances of hazard class 8.
