Chapter 17, Problem 41AE

Interpretation Introduction

Interpretation:

Tin species that can act as oxidizing agent, reducing agent and that is capable to act as both have to be identified and product formed in each case have to be given.

Concept Introduction:

Oxidation refers to phenomenon of loss of electrons; loss of electropositive $\text{H}$ and gain of electronegative $\text{O}$ and substance oxidized is termed as reducing agent.

Reduction is process that involves gain of electrons, gain of $\text{H}$ or loss of electronegative $\text{O}$ atom and substance reduced is termed as oxidizing agent.

A reduction half reaction is accompanied by addition of electrons while an oxidation half reaction is accompanied by loss of electrons. A general reduction process that occurs in reduction half-cell is represented as follows:

  ${\text{M}}^{n+}+{\text{e}}^{-}\to \text{Mn}$

A general oxidation process that occurs in oxidation half-cell is represented as follows:

  $\text{M}\to {\text{M}}^{n+}+{\text{e}}^{-}$

Here

$n$ represents number of  electrons gained or lost.
