Which of the following equations represents an oxidizing action of sulphur dioxide?

a

SO2 + 2HNO2 → H2SO4 + 2NO2 + heat

b

2SO2 + 2H2O + O2 → 2H2SO4

c

SO2 + 2H2O + CI2 → H2SO4 + 2HCI

d

SO2 + 2H2S → 3S + 2H2O

e

K2Cr2O7 + H2SO4 + 3SO2 → K2SO4 + Cr2(SO4)3 + H2O

Here is an explanation:

Oxidation Is D Additon Of Oxygen, In D Above, Hydrogen is oxidized 2 Water (since Oxygen Is Added 2 It) While SO2 is been reduced (oxygen has been removed 4rm it) in such reaction SO2 is describe as thex oxidizing agent and H2 the reducing agent

oxidizing action simply means acting as an oxidising agent,since in option C SO2 is being reduced,it therefore acts as an oxidising agent

The question is specifically asking for the Oxidation reaction of SO2 not the whole equation so I think none of the answers are correct ❌
Even by considering option D' , SO2 is reduced and 2H2S is oxidized but remember the question is specific and not generalized by the whole question



Also Note: Oxidation (gain of oxygen, loss of Hydrogen, loss of electron)
Reduction (loss of Oxygen, gain of Hydrogen, gain of electron)
