List some common processes that involve redox reactions.

Interpretation Introduction

Interpretation:

Some common processes that involve redox reactions are to be listed.

Concept Introduction:

Oxidation is the addition of an electronegative element or the removal of an electropositive element in the chemical reaction.

Reduction is the addition of an electropositive element or the removal of an electronegative element in the chemical reaction.

The chemical reaction in which oxidation and reduction takes place simultaneously is called a redox reaction.

An oxidizing agent is a substance that has the capacity to oxidize the other substances and get reduced in a chemical reaction.

A reducing agent is a substance that has the capacity to reduce the other substances and get oxidized in a chemical reaction.

Explanation of Solution

The chemical equation for the respiration reaction is as follows:

C6H12O6+6O26CO2+6H2O

An oxidizing agent gains electrons easily and a reducing agent loses electrons easily in a chemical reaction.

C60H12+1O62+6O206C+4O22+6H2+1O2

In this chemical reaction, the oxidation state of C6H12O6 increases from 0 to +4 and loss of the electrons occurs. Therefore, C6H12O6 is oxidized in this reaction.

In this chemical reaction, the oxidation state of O2 reduces from 0 to 2 and the gain of electrons occurs. Therefore, O2 is reduced in this reaction.

The chemical equation for the photosynthesis reaction is as follows:

6CO2+6H2OC6H12O6+6O2

An oxidizing agent gains electrons easily and a reducing agent loses electrons easily in a chemical reaction.

6C+4O22+6H2+1O2C60H12+1O62+6O20

In this chemical reaction, the oxidation state of H2O increases from 2 to 0 and the loss of electrons occurs
