Question

The reaction is cl2=cl-+clo3-
A) oxidation
B)Reduction
C)Disproportionation
D) Neither oxidation or reduction

Answer 1

reduction
i hope help this answer

Answer 2

Answer: C) Disproportionation

Explanation:

Oxidation is a reaction in which an element loses electrons and thus the oxidation number of the element increases.

Reduction is a reaction in which an element gains electrons and thus the oxidation number of the element decreases.

Disproportionation is a reaction in which an element undergoes oxidation as well as reduction. Thus the oxidation state of the element decreases as well as increases.

$Cl_2\rightarrow Cl^-+ClO_3^-$

Oxidation state of Cl in  $ClO_3^-$ is x+3(-2)=-1, x=+5

Thus $Cl_2$ is in zero oxidation state reduces to -1 oxidation state in $Cl^-$ and increases to +5 in $ClO_3^-$.
