Question:
Use data from Table 19.1 to predict whether, to any significant extent,
(a) Mg(s) will displace Pb2+ from aqueous solution;
(b) Sn(s) will react with and dissolve in 1 M HCl;
(c) SO42- will oxidize Sn2+ to Sn4+ in acidic solution;
(d) MnO4-(aq) will oxidize H2O2(aq) to O2(g) in acidic solution;
(e) I2(s) will displace Br-(aq) to produce Br2(l).
