Be sure to answer all parts. determine what redox reaction, if any, occurs (at 25°c) when lead metal (pb) is added to
(a) a 1.0 m solution of cocl2 and (b) a 1.0 m solution of hcl. (a) pb is added to a 1.0 m solution of cocl2 pb(s) + co2+(aq) → pb2+(aq) + co(s) pb2+(aq) + 2cl−(aq) → pb(s) + cl2(g) co2+(aq) + 2cl−(aq) → co(s) + cl2(g) no reaction.
(b) pb is added to a 1.0 m solution of hcl pb(s) + 2h+(aq) → pb2+(aq) + h2(g) pb2+(aq) + 2cl−(aq) → pb(s) + cl2(g) pb(s) + 2h2o(l) → pb(oh)2(s) + h2(g) no reaction.
