Answer: Elements Calcium (Ca) and Lithium (Li ) are getting oxidized and elements oxygen [tex](O_2)[/tex] and fluorine [tex](F_2)[/tex] are getting reduced.
Explanation: Oxidized species are the ones which undergo oxidation reaction that means the species which loose their electrons. The oxidation state of these species gets increased. These species tends to form cations (having positive charge).
Reduced species are the ones which undergo reduction reaction that means the species which gain electrons. The oxidation state of these species gets reduced. These species tends to form anions (having negative charge).
In a given chemical reaction:
[tex]2Ca(s)+O_2(g)+F_2(g)+2Li(s)\rightarrow 2LiF(s)+2CaO(s)[/tex]
Reactant side:
Oxidation state of Calcium = 0
Oxidation state of Oxygen = 0
Oxidation state of Fluorine = 0
Oxidation state of Lithium = 0
Product side:
Oxidation state of Calcium = +2
Oxidation state of Oxygen = -2
Oxidation state of Fluorine = -1
Oxidation state of Lithium = +1
From the above information, we can see that oxidation state of calcium and lithium is increasing. Hence, they are getting oxidized.
Similarly, the oxidation state of fluorine and oxygen is decreasing. Hence, they are getting reduced.
Based on the nature of oxidation-reduction reactions;
- Ca is oxidized to Ca2+ while O is reduced to O2-
- F2 is reduced to F- while Li is oxidized to Li+
What are oxidation and reduction reactions?
Oxidation-reduction reactions are reactions in which oxidation and reduction of reacting species occurs concurrently to the same extent.
Oxidation involves loss of electrons and increase in oxidation number.
Reduction involves gain of electrons and decrease on oxidation number.
In the given reaction:
- 2 Ca (s) + O2 (g) → 2 CaO (s)
- F2 (g) + 2 Li (s)→ 2 Lif (s)
Ca is oxidized to Ca2+ while O is reduced to O2-
F2 is reduced to F- while Li is oxidized to Li+
