Redox Help...?

Question

For the reaction, S2O3 (-2) + H2O -> HS ( -) + HSO3, please answer the following:
a) is this a redox reaction?
b) which species is reduced? (be very specific)
c) which species is oxidized? (be very specific)
d) which species is the oxidizing agent? (be very specific)

- Basically, can it be a redox reaction if the same thing is being oxidized and reduced? And if it is, wouldn't Sulfur be the answer for B, C, and D?

Answer 1

a) is this a redox reaction? Yes
b) which species is reduced? (be very specific) S2O3
c) which species is oxidized? (be very specific) S2O3
d) which species is the oxidizing agent? (be very specific) S2O3
Can it be a redox reaction if the same thing is being oxidized and reduced? Yes.
If it is, wouldn't Sulfur be the answer for B, C, and D? No, it should be S2O3 (-2).
