Chapter 7, Problem 41QAP

Interpretation Introduction

Interpretation:

To determine what an oxidation −reduction reaction is and what is transferred in such reaction.

Concept Introduction:

The most common driving forces which create product in chemical reactions are as follows:

1. Formation of a solid.
2. Formation of water.
3. Transfer of electrons.
4. Formation of gas.

Oxidation-reduction reaction is known as redox reaction. In these types of reaction one reactant is oxidized and another is reduced.

Oxidation: Oxidation is a process in which either 1 or all following changes occurs:

1. Gaining of oxygen atoms.
2. Increasing oxidation number.
3. Loss of hydrogen atom.
4. Loss of electrons.

Reduction: Reduction is a process in which either 1 or all following changes occurs:

1. Loss of oxygen atoms.
2. Decreasing oxidation number.
3. Gaining of hydrogen atom.
4. Gaining of electrons.
