Can anyone help me with this question:
Explain, in terms of electron transfer, why bromine is the oxidant (oxidising agent) in this reaction

Br2(aq) + S2–(aq) → 2Br –(aq) + S(s)
Br2(aq) + S2–(aq) → 2Br –(aq) + S(s)

Okay so the oxidation state of bromine went from 0 to -2 whereas the oxidation state of sulfur went from -2 to 0. Therefore, bromine is the oxidising agent because it’s the one being reduced and accepts electrons

Each bromine atom changed from 0 to -1.

But hasn't the bromine lost electrons and the sulfur the one gaining electrons?

Bromide ions are in the -1 oxidation state.
0 to -1 is gain of one electron.

But then how is Sulfur not gaining electrons. Sorry this is confusing me. I now understand the part about bromine, but not sulfur
