Oxidation-Reduction Reactions in the Environment
Oxidation—reduction redox reactions — reactions that are connected with electrons transfer from the atom oxidized to the atom reduced. Redox processes — processes where electron transfer between donors and acceptors take place and in any redox transformations causing oxidation states of the two components. Numerous processes from the microenvironment to the macro environment scale dependent to their redox conditions where dynamics are connected with serious oxidation—reduction reactions and can be expressed by redox potential E h or by free electron pressure pe showing the tendency of an environment to receive or to supply electrons in water solution.

Oxidation and Reduction in Organic Chemistry
An organic compound commonly is said to be "reduced" if reaction leads to an increase in its hydrogen content or a decrease in its oxygen content. The compound would be "oxidized" if the reverse change took place:. This is a very unsatisfactory definition because many oxidation-reduction or redox reactions do not involve changes in hydrogen or oxygen content, as the following example illustrates:. Redox reactions are better defined in terms of the concept of electron transfer. Thus an atom is said to be oxidized if, as the result of a reaction, it experiences a net loss of electrons; and is reduced if it experiences a net gain of electrons.
Oxidation and reduction reactions will come up over and over in your organic chemistry course. You may remember redox from general chemistry as the topic involving half-cells, batteries, and metals with changing oxidation numbers. Download my Orgo Redox cheat sheet to follow along and try the redox practice quiz. This video introduces the concept of redox at the organic chemistry level. Examples include redox of alkenes, alkynes, alcohols and more, as well as what to look out for when faced with an unfamiliar reagent.
You are undoubtedly already familiar with the general idea of oxidation and reduction: you learned in general chemistry that when a compound or element is oxidized it loses electrons, and when it is reduced it gains electrons. You also know that oxidation and reduction reactions occur in tandem: if one species is oxidized, another must be reduced at the same time - thus the term 'redox reaction'. Most of the redox reactions you have seen previously in general chemistry probably involved the flow of electrons from one metal to another, such as the reaction between copper ion in solution and metallic zinc:. Reading the reaction above from left to right, which chemical species is being oxidized? Which is being reduced?

Oxidation-reduction reaction , also called redox reaction , any chemical reaction in which the oxidation number of a participating chemical species changes. 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.
Тайна имела первостепенное значение. Любое подозрение об изменении Цифровой крепости могло разрушить весь замысел коммандера. Только сейчас она поняла, почему он настаивал на том, чтобы ТРАНСТЕКСТ продолжал работать.
- Он усмехнулся. - Я попросил Фонтейна передать его наследникам Танкадо. - Он взял ее руку и натянул что-то на палец. - Лжец, - засмеялась Сьюзан, открывая .
- Клянусь, я сделаю .
