Options:
A) $ FeCl_3 $ acts as an oxidising agent
B) Both $ H_2S $ are $ FeCl_3 $ are oxidized
C) $ FeCl_3 $ is oxidised while $ H_2S $ is reduced
D) $ H_2S $ acts as an oxidising agent.
Show Answer
Answer:
Correct Answer: A
Solution:
[a] In $ 2FeCl_3+H_2S\to 2FeCl_2+2HCl+S $ O.N. of S changes from -2 to 0 (hence oxidised) O.N. of Fe changes from +3 to +2 hence reduced.
