Answer : The balanced chemical equation in a basic solution are,
(A)
(B)
(C)
(D)
Explanation :
<u>(A) The given chemical reaction is :</u>
The oxidation-reduction half reaction will be :
Oxidation :
Reduction :
In order to balance the electrons, we multiply the oxidation reaction by 3 and reduction reaction by 2 then added both equation, we get the balanced redox reaction.
The balanced chemical equation in a basic solution will be,
or,
<u>(B) The given chemical reaction is :</u>
The oxidation-reduction half reaction will be :
Oxidation :
Reduction :
The electrons in both the reactions are balanced. Now added both equation, we get the balanced redox reaction.
