In the redox reaction of SO2 with KMnO4 for an acidic medium:
- A
SO2 oxidizes KMnO4
- B
SO2 reduces KMnO4
- C
KMnO4 is inert in acidic medium
- D
SO2 can't undergo redox reaction
Option B is correct as SO2 is a strong reducing agent and KMnO4 is a strong oxidising agent. SO2 reduces Mn7+ in KMnO4 to Mn2+ and gets oxidised itself from S4+ to S6+.
SO2 is a strong reducing agent and reduces Mn7+ in KMnO4 Mn2+.
SO2 is a strong reducing agent and KMnO4 is a strong oxidising agent. SO2 reduces Mn7+ in KMnO4 to Mn2+ and gets oxidised itself from S4+ to S6+.
KMnO4 is a strong oxidising agent in its acidic medium.
This reaction undergoes redox reaction where S in SO2 gets oxidised and Mn in KMnO4 gets reduced.
