Chapter 15, Problem 15.64AQAP

Interpretation Introduction

(a)

Interpretation:

The given redox chemical equation in acidic medium should be balanced.

  $S{n}_{}^{\text{2+}}{\text{(aq)+IO}}_4^{-}\text{(aq)}\underset{}{\to }S{n}_{}^{4+}{\text{(aq)+I}}^{\text{-}}\text{(aq)}$

Concept Introduction:

A redox reaction is a chemical reaction in which oxidation and reduction reactions takes place simultaneously. In such type of reaction one of the chemical species is getting oxidized while the other species gets reduced at the same time.

Oxidation state or oxidation number of an atom is defined as the positive or the negative charge that an atom would possess if it is present as ions in the given compound. In such type of reaction, the oxidation state of the atom undergoing oxidation will increase which depends upon the number of electrons lost by a particular atom. Reduction of a chemical species refers to the gain of electrons by the chemical species which results in decrease in oxidation state of that atom.
