  <name>Phosphoric acid</name>
  <description>Phosphoric acid, also known as phosphate or [po(OH)3], belongs to the class of inorganic compounds known as non-metal phosphates. These are inorganic non-metallic compounds containing a phosphate as its largest oxoanion. Phosphoric acid exists as a solid, possibly soluble (in water), and a moderately acidic compound (based on its pKa) molecule. Phosphoric acid exists in all living species, ranging from bacteria to humans. Phosphoric acid is a potentially toxic compound.</description>
