Phosphate radical
The -OH groups in phosphoric acids can also condense with the hydroxyl groups of alcohols to form phosphate esters. Since orthophosphoric acid has three -OH groups, it can esterify with one, two, or three alcohol molecules to form a mono-, di-, or triester. See the general structure image of an ortho- (or mono-) phosphate ester below on the left, where any of the R groups can be a hydroge… WebPhosphate radicals in the three acid-base forms, H/sub 2/PO/sub 4/, HPO/sub 4//sup -/, and PO/sub 4//sup 2 -/, were produced by the reaction of hydrated electrons with peroxodiphosphate ions at pH values of 3-4, 7-9, and 12, respectively. Rate constants for the reactions of these radicals with organic compounds were determined by following the ...
