Chapter 24, Problem 36E

Interpretation Introduction

Interpretation:

The oxidation of ${\left[Co{\left(N{H}_3\right)}_6\right]}^{2+}$ to ${\left[Co{\left(N{H}_3\right)}_6\right]}^{3+}$ should occur spontaneously in alkaline solution with $H_2{O}_2$ as an oxidizing agent should be determined.

Concept introduction:

The procedure in which an atom, molecule or ionspends one or more electrons is called oxidation and in the process in which itacquires one or more electrons is called reduction.The element which loses electrons is said to be oxidized and which obtains electrons is said to be reduced.

A constituent which oxidizes others but itself experiences reduction is known as an oxidizing agent or oxidant, and a substance which undergoes oxidation but reduces others is known as reducing agent. $H_2{O}_2$ is an important oxidizing agent and H₂ is an example of reducing agent.
