Phosphinates or hypophosphites are a class of phosphorus compounds conceptually based on the structure of hypophosphorous acid. IUPAC prefers the term phosphinate in all cases, however in practice hypophosphite is usually used to describe inorganic species (e.g. sodium hypophosphite), while phosphinate typically refers to organophosphorus species.

Hypophosphites

[edit]

The hypophosphite ion is (H
2PO
2)−
. The salts are prepared by heating white phosphorus in warm aqueous alkali e.g. Ca(OH)2:[1]

P4 + 2 Ca(OH)2 + 4 H2O → 2 Ca(H2PO2)2 + 2 H2

Hypophosphites are reducing agents:[1]

(H
2PO
2)−
 + 3 OH− → (HPO
3)2−
 + 2 H2O + 2 e−

Hypophosphites are used in electroless nickel plating as the reducing agent to deposit for example Ni metal from Ni salts.[1] The hypophosphite ion is thermodynamically unstable, and disproportionates on heating to phosphine and phosphate salts:

2 H
2PO
2−
 → PH3 + HPO
42−

One thought on “Cannabaceae”

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
