How is pyrophosphoric acid related to orthophosphoric acid?

Text Solution

AI Generated Solution

To understand the relationship between pyrophosphoric acid and orthophosphoric acid, we can break down the explanation into several steps: ### Step 1: Definition of Orthophosphoric Acid Orthophosphoric acid, also known as phosphoric acid, is a triprotic acid with the chemical formula H₃PO₄. It consists of one phosphorus atom bonded to four oxygen atoms, three of which are connected to hydrogen atoms. ### Step 2: Definition of Pyrophosphoric Acid Pyrophosphoric acid is a diphosphoric acid with the chemical formula H₄P₂O₇. It is formed from two molecules of orthophosphoric acid. ...
