The oxidation of the bisulfide ion by dissolved oxygen to produce the sulfate ion involves the formation of a previously undetected intermediate. This intermediate has a fairly strong Raman band at 1090 wave numbers and a weak Raman band at 740 wave numbers, both of which are probably due to sulfur-oxygen stretches. The intermediate is proposed to be the disulfate ion S/sub 2/O/sub 7//sup 2 -/, which hydrolyzes into H/sup +/ and either SO/sub 4//sup 2 -/ or HSO/sub 4//sup 2 -/ with a half-life of about 52 seconds at 25/sup 0/C.
