Which of the following is an oxidation-reduction reaction? Which of the following is an oxidation-reduction reaction? Ca(s) + 2 HI(aq) → CaI2(aq) + H2(g) LiCl(aq) + AgNO3(aq) → AgCl(s) + LiNO3(aq) HI(aq) + NaOH(aq) → NaI(aq) + H2O(l) Pb(C2H3O2)2(aq) + 2 LiI(aq) → PbI2(s) + 2 LiC2H3O2(aq) All of the above are oxidation-reduction reactions.
