A lead wire is placed in a solution containing Cu2+ yes Pb2+ no Cu no PbO2 Cl2 gas is bubbled into a solution of Nal. yes 12 noc no No reaction A silver wire is placed in a solution containing Cu2+ yes No reaction no Ag2+ no cu Submit Answer Incorrect.

Answer 1

According to reactivity series more reactive metal oxidise itself and reduce other metal.

1. Pb is more reactive than Cu so it displace Cu​​​​​2+ form the solution as a result Cu and Pb​​​​​2+ is produced.
2. Cl displace I , as a result Cl​​​​​- and I2​​​​ is produced.
3. Ag is less reactive than Cu​2+ so there is no reaction.
