Chapter 18, Problem 7QAP

Interpretation Introduction

Interpretation:

Complete the blank with appropriate term.

____ lets us keep track of electrons in oxidation-reduction reactions by assigning charges to the various atoms in a compound.

Concept Introduction:

The chemical reaction in which both oxidation and reduction process takes place is known as redox reaction. In this reaction, transfer of electrons takes place among the elements.

Oxidation is the process in which either loss of electrons, oxidation number increases, or loss of hydrogen atoms takes place. An element is oxidized, when oxidation number increases.

Reduction is the process in which either gain of electrons, oxidation number decreases, or gain of hydrogen atoms takes place. An element is reduced, when oxidation number decreases.
