I don't know about the over voltage associated with these ions. Over voltage not withstanding, H2 at the cathode and O2 at the anode. S(s) (from S^2-) is VERY close.

H2 (g) is produced at the cathode. S (s) is produced at the anode. Just compare reduction potentials.

H2 (g) at cathode
S (s) at anode
S (s) at anode
