fosfoorihappoon

Fosforihappo is the Finnish name for phosphoric acid, a mineral acid with the chemical formula H3PO4. It is a triprotic acid, meaning it can donate three protons. In its pure form, it is a white solid, but it is typically encountered as a colorless aqueous solution. Phosphoric acid is a key industrial chemical, produced on a large scale primarily for use in fertilizers. Approximately 90% of all phosphoric acid produced is consumed by the fertilizer industry.

Beyond its agricultural applications, phosphoric acid has several other uses. It is employed as a food additive, where it acts as an acidulant, flavor enhancer, and preservative, particularly in cola beverages. It is also used in rust removal, as a dental and orthopedic etching agent, in the production of detergents, and in the refining of sugar and vegetable oils.

Phosphoric acid is a relatively weak acid compared to strong mineral acids like sulfuric or hydrochloric acid. It is considered non-toxic in the concentrations typically found in food and beverages, although it can be corrosive in higher concentrations. The human body contains phosphorus, an essential element, and phosphoric acid plays a role in various biological processes, including energy metabolism and DNA structure.
