This section does not have problem sets or activities, but will provide definitions you may want to refer back to as you are doing the other sections of this chapter. I am writing this section to help students who have not had physics and hope it will help make the other sections easier to understand.
The electron transfer may be between two different chemical species, or between atoms of the same species. This chapter introduces electrochemistry, which is the study of redox reactions.

Redox Reactions in terms of Electron Transfer [2]

A variety of chemical and biological reactions like burning of different types of fuels (wood, kerosene, coal, LPG, petrol, diesel), digestion of food in animals, photosynthesis by plants, extraction of aluminum from alumina, electricity generation from batteries or cell, rusting of iron fall in the category of redox reaction.. Redox reaction is a type of chemical reaction in which oxidation and reduction take place simultaneously
As shown in the below equation, here sodium(Na) is oxidized as well as hydrogen(H) is reduced. So, their oxidation, as well as reduction, takes place simultaneously
This reaction is used in pharmaceuticals, biological, industrial, metallurgical and agricultural areas.. – Oxidation: It is defined as the addition of oxygen/electronegative elements to a substance or removal of hydrogen/electropositive elements from a substance.

Chapter 11 – Electron Transfer Reactions and Electrochemistry [3]

Chapter 11 – Electron Transfer Reactions and Electrochemistry. IntroductionRedox, or electron transfer, reactions constitute one of the broadest and most important classes of reactions in chemistry
Biological processes, such as respiration, photosynthesis, and the breakdown of food molecules, consist of sequences of electron transfer reactions that serve to transport and utilize energy from the sun. Batteries are devices that allow us to utilize the free energy of electron transfer reactions.
•4.2 Orbital Occupancies of Ions Exercise (Determine the electron occupancy of an ion from the occupancy of its atom and vice versa.). •4.4 Oxidation States (Determine the oxidation states of the atoms in a compound or ion.)

What’re the four types of chemical reactions? [5]

Proton transfer reactions occur when a proton is transferred from an acid to a base.. The most abundant form of hydrogen has one proton and one electron
When this happens, we usually say a proton has been transferred. Sometimes the symbol, H+, is used to describe proton transfer when we write chemical equations for acid-base reactions
Electron transfer reactions occur when one atom loses an electron to another atom. The atom that loses the electron is said to go through oxidation

Biology for Majors I [6]

Understand the role movement of electrons plays in energy exchanges in cells. Energy production within a cell involves many coordinated chemical pathways
An oxidation reaction strips an electron from an atom in a compound, and the addition of this electron to another compound is a reduction reaction. Because oxidation and reduction usually occur together, these pairs of reactions are called oxidation reduction reactions, or redox reactions.
– Describe how cells store and transfer free energy using ATP. You’ve just been given a big, juicy glucose molecule, and you’d like to convert some of the energy in this glucose molecule into a more usable form, one that you can use to power your metabolic reactions

Electron Transfer [7]

The concept of oxidation arises from the combination of elemental oxygen with other elements to form oxides, as in this example using aluminum:. With oxidation numbers inserted as superscripts, this reaction is written
Because the oxidation numbers changed, an oxidation‐reduction reaction is defined as one in which electrons are transferred between atoms. In the example, each oxygen atom has gained two electrons, and each aluminum has lost three electrons.
In the aluminum‐oxygen example, the aluminum was oxidized, and the oxygen was reduced because every electron transfer reaction involves simultaneous oxidation and reduction. These reactions are frequently called redox reactions.

Our editors will review what you’ve submitted and determine whether to revise the article.. – electrochemical reaction combustion oxidation number reduction Cannizzaro reaction
The term covers a large and diverse body of processes. Many oxidation-reduction reactions are as common and familiar as fire, the rusting and dissolution of metals, the browning of fruit, and respiration and photosynthesis—basic life functions.
Both reciprocity and net change are illustrated below in examples of the three most common types of oxidation-reduction reactions.. Carbon reacts with mercury(II) oxide (a compound in which mercury has a bonding capacity expressed as +2; see below Oxidation-state change) to produce carbon dioxide and mercury metal

Lesson Explainer: Redox Reactions [10]

In this explainer, we will learn how to identify redox reactions and write ionic equations to describe electron transfer between oxidants and reductants.. A redox reaction is a combination of a reduction and an oxidation.
A reduction involves gaining electrons, while an oxidation involves losing electrons. In a redox reaction, electrons are transferred from one species to another
A reduction is any chemical reaction where a chemical species gains electrons.. An oxidation is any chemical reaction where a chemical species loses electrons.

Oxidation-Reduction (Redox) Reactions [11]

It is fairly obvious that zinc metal reacts with aqueous hydrochloric acid! The bubbles are hydrogen gas.. Source: Photo courtesy of Chemicalinterest, http://commons.wikimedia.org/wiki/File:Zn_reaction_with_HCl.JPG.
This is one example of what is sometimes called a single replacement reaction because Zn replaces H in combination with Cl.. Because some of the substances in this reaction are aqueous, we can separate them into ions:Zn(s) + 2H+(aq) + 2Cl−(aq) → H2(g) + Zn2+(aq) + 2Cl−(aq)
(There is no net change experienced by the chloride ion.) In fact, electrons are being transferred from the zinc atoms to the hydrogen atoms (which ultimately make a molecule of diatomic hydrogen), changing the charges on both elements.. To understand electron-transfer reactions like the one between zinc metal and hydrogen ions, chemists separate them into two parts: one part focuses on the loss of electrons, and one part focuses on the gain of electrons
