Question

Identify the oxidising agent in the following reaction:
1)Pb3O4+8HCl=3PbCl2+Cl2+4H2O
2)ZnO+H2=Zn+H2O
3)3Fe+4H2O=Fe3O4+4H2
4)V2O5+5Ca=2V+5CaO

Answer 1

Answer:

1)Pb3O4 + 8HCl → 3PbCl2 + Cl2 + 4H2O

Oxidizing agent : Pb3O4

2)ZnO + H2 → Zn + H2O

Oxidizing agent : ZnO

3)3Fe + 4H2O → Fe3O4 + 4H2

Oxidizing agent : H2O

4)V2O5 + 5Ca → 2V + 5CaO

Oxidizing agent : V2O5

Explanation:

An oxidizing agent removes electrons from reactants, gains electrons and gets reduced itself.
