What is Phosphoric Acid?

Phosphoric Acid is a colourless, clear viscous liquid mineral acid. It is entirely odourless. In its pure form, Phosphoric Acid is a crystalline solid (although it is rarely distributed in this form). At high concentrations it is classed as a corrosive, however it is easily diluted and is classed as Non-Toxic when mixed with water.

It is also sometimes known as Orthophosphoric Acid in order to distinguish it from related phosphoric acids known as polyphosphoric acids.

The chemical formula for Phosphoric Acid is H3PO4.
