A chemical which donates electrons to other then it is called a reducing agent because the chemical undergoes oxidation and reduces other chemicals. A chemical which accepts electrons from others is called an oxidizing agent because the chemical is going to make others undergo oxidation.
Complete answer:
- In the question is asked to find the role of hydrogen sulphide in the given reaction.
- The given reaction is as follows.
SO2+2H2S→2H2O+3SSO2+2H2S→2H2O+3S
- In the above reaction one mole of sulphur dioxide reacts with two moles of hydrogen sulphide and forms two moles of water and three moles of sulphur as the products.
- The oxidation state of sulphur in sulphur dioxide is
x+2(−2)=0x+2(−2)=0
x=4x=4
Here x = oxidation state of the sulphur on sulphur dioxide.
- The oxidation state of the pure sulphur formed as the product is 0.
- Means the oxidation state of sulphur in sulphur dioxide is 4 and it decreases to ‘0’ after completion of the reaction.
- So, the sulphur dioxide got reduced by accepting electrons from hydrogen sulphide.
- Means sulphur dioxide is a oxidizing agent and hydrogen sulphide is a reducing agent.
- Therefore the role of hydrogen sulphide in the given reaction is a reducing agent.
So, the correct option is B.
Note:
The oxidation state of sulphur in hydrogen sulphide is
x+2(1)=0x+2(1)=0
x=−2x=−2
Here x =oxidation state of sulphur in hydrogen sulphide.
The oxidation state of sulphur in hydrogen sulphide is -2 it is changed to ‘0’ (oxidation state of sulphur produced in reaction as the product). So, hydrogen sulphide is oxidized and acts as a reducing agent in the given reaction.
