Hyposulfite
Not to be confused with hydrosulfite, which is another name for the
dithionite
anion (
S
2
O
2−
4
).
Hyposulfite
may refer to:
The
sulfoxylate
anion (
SO
2−
2
)
The
thiosulfate
anion (
S
2
O
2−
3
)
Sodium thiosulfate
, a salt containing the thiosulfate anion
S
2
O
2−
2
, a reported
sulfur
oxyanion
. However salts containing
S
2
O
2−
2
and
HS
2
O
−
2
are not well characterized; they would be conjugate bases derived from the parent
thiosulfurous acid
(
H
2
S
2
O
2
), which is also of doubtful existence.
Dithionite (
S
2
O
2−
4
) as in sodium dithionite.
