Chapter 18, Problem 18.1QE
Interpretation Introduction

Interpretation:

Oxidation and reduction should be described and also the electron transfer in a redox reaction and electron donation in a Lewis acid-base reaction has to be compared.

Concept Introduction:

Redox reaction and Half-reaction

  • The redox reaction is the combination of oxidation and reduction reactions and these two reactions are called half-reactions.

Oxidation reaction:

  • The loss of electrons or the gain of oxygen atoms is called as oxidation.

Reduction reaction:

  • The gaining of electrons or addition of hydrogen atoms is called as reduction.

Expert Solution & Answer

Explanation of Solution

Oxidation is the reaction in which loss of electron occurs and reduction reaction is the reaction in which gain of electron occurs. Redox reaction is a common term used for a reduction and an oxidation reaction.

In a redox reaction, oxidation always accompanies reduction. Thus one atom must lose electrons and other must gain electrons.

Oxidation reaction:

  Ag  Ag++ e-

In the above reaction, Ag atom loses one electron and changes their oxidation state 0 to 1.

Reduction reaction:

  Fe2++2e-  Fe

In the above reaction Fe2+ ion gaining 2 electrons and reduce their oxidation number +2 to 0.

According to Lewis concept of acid and bases,

Lewis acid is an electron pair acceptor.

Lewis base is an electron pair donor.
