Asappp in which of the following reactions is chlorine (ci) oxidized? a. br2 + 2ci” = ci2 +2br” b. ci2 + 2e” = 2ci” c. 2cio3” + 12h+ = ci2 + 6h2o d. 2na + ci2 = 2naci

Option (A) is the correct answer.

Explanation:

When there is an increase in oxidation state or release of electron from an atom then this process is known as oxidation.

In the reaction, , the oxidation and reduction equations are as follows.

Reduction:  

Oxidation:  

Also, in the above reaction, oxidation state of chlorine increases from -1 to 0. Therefore, chlorine is oxidized in this reaction.

In the reaction, , the oxidation state of chlorine reduces from 0 to -1. Therefore, chlorine is reduced in this reaction.

In the reaction, , the oxidation state of chlorine reduces from +6 to 0. Therefore, chlorine is reduced in this reaction.

In the reaction, , the oxidation state of chlorine reduces from 0 to -1. Therefore, chlorine is reduced in this reaction.
