Chemical compound
Phosphinous acid is the inorganic compound with the formula H2POH. It exists, fleetingly, as a mixture with its less stable tautomer H3PO (phosphine oxide)

Class of chemical compounds
R2P(O)OH + H2O These reactions are preceded by tautomerization to the phosphinous acid (R2POH): R2P(O)H → R2POH R2POH + H2O2 → R2PO2H + H2O A nonoxidative

 English form of Welsh Kai, KAY means "lord." In Arthurian legend, this is the name of one of the first Knights of the Round Table. He was the son of Sir Ector, the foster brother of King Arthur, and is noted for having an acid tongue and boorish behavior, but mostly for trying to take credit when Arthur pulled the sword from the stone. Compare with another form of Kay.Â
