Phosphorus triiodide (PI 3) is an inorganic compound with the formula PI 3. A red solid, it is too unstable to be stored for long periods of time; it is, nevertheless, commercially available. [ 2 ] It is widely used in organic chemistry for converting alcohols to alkyl iodides and also serves as a powerful reducing agent.

Phosphorus is 0.1% of the earth's crust, making it the 11th most abundant element. Phosphorus comprises 0.65 parts per million of soil and 15 to 60 parts per billion of seawater. There are 200 Mt of accessible phosphates on earth. Phosphorus makes up 1.1% of a typical human by weight. [14]
A general formula for such cyclic compounds is [HPO 3] x where x = number of phosphoric units in the molecule. When metaphosphoric acids lose their hydrogens as H +, cyclic anions called metaphosphates are formed. An example of a compound with such an anion is sodium hexametaphosphate (Na 6 P 6 O 18), used as a sequestrant and a food additive.
