Redox Reactions And Electrochemistry Question 223
Question: $ H_2S $ acts only as a reducing agent while $ SO_2 $ can act both as a reducing and oxidizing agent because [AMU 1999]
Options:
A) $ S $ in $ H_2S $ has - 2 oxidation state
B) $ S $ in $ SO_2 $ has oxidation state + 4
C) Hydrogen in $ H_2S $ more +ve than oxygen
D) Oxygen is more - ve in $ SO_2 $
Show Answer
Answer:
Correct Answer: A
Solution:
In $ H_2S $ sulphur shows -2 oxidation state and in $ SO_2 $ shows +4 oxidation state. Hence $ SO_2 $ shows both oxidising and reducing properties.
