Question

identify the substance that are oxidized and reduced in the following reaction 1. H2+br2-2hbr​

Answer 1

Answer:

In this reaction, sulfur in H2S is replaced by Br. It means that H2S has lost hydrogen, Therefore, the equation shows that hydrogen sulfide (H2S) compound is being oxidized in this chemical reaction and bromine is reduced into HBr.

Answer 2

Answer:

H₂S is oxidised and Br₂ is reduced.

Explanation:

Assuming the complete equation to be:
H₂S+Br₂→2HBr+S

We know that the oxidation state of H is +1.

∴In H₂S

(2)+S=0

∴S=-2

In Br₂

Br=0

In HBr,

1+Br=0

∴Br=-1

In S, S=0

Therefore, sulphur is oxidised from -2 to 0 and bromine is reduced from 0 to -1.

Thus, H₂S is oxidised and Br₂ is reduced.
