Phosphoric acid, scientifically known as orthophosphoric acid (H3PO4), is a mineral acid derived from phosphorus. Its production can be achieved through two main methods: the wet process, involving the reaction of phosphate rock with sulfuric acid, and the thermal process, which burns elemental phosphorus. The resulting 85% concentration is a common and highly utilized form, appreciated for its moderate strength and relatively low volatility compared to other strong acids.

The chemical properties of phosphoric acid are key to its widespread application. As a triprotic acid, it can donate three protons, allowing for versatile pH control and participation in various chemical reactions. Its molecular structure, featuring a central phosphorus atom bonded to three hydroxyl groups, grants it excellent solubility in water and polar solvents, and remarkable chemical stability under normal storage conditions. These characteristics make it a preferred choice for many applications.

When considering the safe handling of phosphoric acid, several precautions are essential. While it is generally regarded as safe (GRAS) by regulatory bodies like the FDA when used as a food additive, concentrated solutions are corrosive. Proper personal protective equipment (PPE), including chemical-resistant gloves, eye protection, and protective clothing, should always be used. Adequate ventilation is crucial to avoid inhaling vapors. It is important to store phosphoric acid in appropriate containers, typically made of high-density polyethylene or glass, and keep them tightly closed.

The health impact of phosphoric acid is primarily linked to excessive intake, particularly through processed foods and sodas, which can lead to imbalances in phosphorus and calcium levels, potentially affecting bone health and kidney function. However, when used as intended in food and industrial applications, and handled with care, it poses minimal risk. Understanding the phosphoric acid chemical properties and employing diligent safety measures ensures its effective and safe use.
