Which element is reduced in the reaction below? A. Na B. CI C. Ba D. None
2 answers:
<u>Answer:</u> The correct answer is Option D.
<u>Explanation:</u>
For the given chemical reaction:
The above chemical reaction is considered as double displacement reaction because here exchange of ions takes place.
In these type of reactions, oxidation state of the atoms remains the same.
<u>On the reactant side:</u>
Oxidation state of barium = +2
Oxidation state of chlorine = -1
Oxidation state of sodium = +1
<u>On the product side:</u>
Oxidation state of barium = +2
Oxidation state of chlorine = -1
Oxidation state of sodium = +1
Thus, the correct answer is Option D.
