What is Phosphoric Acid?

Phosphoric acid, also known as orthophosphoric acid, is a colourless and viscous liquid mineral acid. It is also entirely odourless. In its pure form, phosphoric acid is a crystalline solid, although it is rarely distributed in this form. Highly concentrated phosphoric acid is classed as a corrosive. However, it is easily diluted and is classed as non-toxic when mixed with water.

The alternative term, orthophosphoric acid, is sometimes used in order to distinguish it from related phosphoric acids known as polyphosphoric acids.
