Question

Which of the following conversions requires an oxidizing agent?

O2 2O2-

SO3 SO42-

MnO2 Mn2+

Zn Zn2+

Answer 1

oxdising agent is a substance which excepts the electron from the following conversion

Answer 2

Can you write the oxidation state in all these cases for O ,S, Mn and for Zn

Answer 3

O2 -------------> 2O2- it is gaining 2 electrons so it is undergoing reduction so requires oxidizing agent
SO3 ---------->SO42- it is gaining 2 electrons and 1 O atom so it is undergoing reduction so requires oxidizing agent
MnO2 ---------> Mn2+ it is loosing electrons so it i undergoing oxidation so requires reducing agent
Zn -------> Zn2+ it is loosing 2 electrons so undergoes oxidation and requires reducing agent
Hope that helped!!
