Respuesta :

No. Oxidation number is still I

Answer: No, the oxidation state of hydrogen does not change in the given chemical reaction.

Explanation: Balancing the given chemical equation, we get:

[tex]2HBr+H_2SO_4\rightarrow SO_2+Br_2+2H_2O[/tex]

Reactant side:

In HBr, the oxidation state of bromine is -1, so to form a neutral compound, hydrogen should have an oxidation state of +1.

In [tex]H_2SO_4[/tex] , the oxidation state of sulfate is -2, so to form a neutral atom, two hydrogen atoms having +1 oxidation state should combine with it.

Product side:

In [tex]H_2O[/tex], the oxidation state of hydroxide ion is -1, so to form a neutral water molecule, hydrogen should have an oxidation state of +1.

From above, we can say that the oxidation states of hydrogen atom did not change for the following chemical reaction.
