Question

1) Which ones of the following are oxidizing agents? Pick all that apply.

a) Cr₂O₇^2-

b) Zn

c) H₂O₂

d) Cr

e) None of the Above

2) Which ones of the following are reducing agents? Pick all that apply.

1) H₂O₂

2) C

3) Br₂

4) Al

E) None of the Above

Answer 1

1. Oxidizing agents are species which oxidizes other reactants and themselves get reduced in the process.

Cr2O7^2- is an oxidizing agent. Compounds with large oxidizing state act as good oxidizing agent.

H2O2 acts as both oxidizing and reducing agent.

2. Reducing agent are species which reduces other reactants while themselves getting oxidized in the process.

H2O2 acts as a reducing agent.

Carbon is used as a reducing agent in metallurgy.

Aluminium acts as a good reducing agent as it has great affinity for oxygen.
