Question

In which of the following reactions is chlorine (Cl) oxidized? Br2 + 2Cl− → Cl2 + 2Br− Cl2 + 2e− → 2Cl− 2ClO3− + 12H+ → Cl2 + 6H2O 2Na + Cl2 → 2NaCl
PLEASE HELP

Answer 1

2CIO3 is the answer to your question

Answer 2

Answer: $Br_2+2Cl^-\rightarrow Cl_2+2Br^-$

Explanation:

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

$Br_2+2Cl^-\rightarrow Cl_2+2Br^-$

On reactant side:

Oxidation state of chlorine = -1

On product side:

Oxidation state of chlorine = 0

The oxidation state of chlorine increases from -1 to 0. Thus, it is getting oxidized and it undergoes oxidation reaction.
