2H2S + SO2 → 2H2O + 3S write the reduced product
Answers
Explanation:
The given reaction is a type of redox reaction.
Redox reaction is defined as the reaction in which oxidation and reduction reaction occur simultaneously.
Oxidation reaction is defined as the reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.
Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
From the above given reaction:
H2S→S+2H++2e−
Oxidation state of Sulphur changes from -2 to 0
Sulfide has been oxidized, and sulfur dioxide is the oxidizing agent.
from SO2→2S
oxidation state changes from +4 to 0
So H2S gets oxidized and SO2 gets reduced.
I hope my answer helps you....✌
Følløw me
2H2S+SO2=2H2O+3S
In reduction gain of electrons take place.
SO2 get reduced to S.
