Ok so i looked at it and tried to figure out the conj. base and acid. Are these right?

1) S2-(aq) + HCl(aq) <=>Cl1-(aq) + HS1-(aq)
This is what I think it is:
Acid = HCl
Base = S^2-
Conjugate acid =HS^1-
Conjugate base = Cl^1-

2) H2O2(aq) + PO43-(aq) <=>HPO42-(aq) + HO21-(aq)
This is what I think it is:
Acid = H2O2
Base = PO4^3-
Conjugate acid =HPO4^2-
Conjugate base = HO2^1-

3) IO31-(aq) + HI(aq)<=> I1-(aq) + HIO3(aq)
This is what I think it is:
Acid = HI
Base = IO3
Conjugate acid =HIO3
Conjugate base = I^1-

Those look ok to me.
