Redox short for reduction—oxidation reaction pronunciation: Any such reaction involves both a reduction process and a complementary oxidation process, two key concepts involved with electron transfer processes. The chemical species from which the electron is stripped is said to have been oxidized, while the chemical species to which the electron is added is said to have been reduced.
It can be explained in simple terms:. As an example, during the combustion of wood, oxygen from the air is reduced, gaining electrons from carbon which is oxidized. The reaction can occur relatively slowly, as with the formation of rust , or more quickly, in the case of fire.
There are simple redox processes, such as the oxidation of carbon to yield carbon dioxide CO 2 or the reduction of carbon by hydrogen to yield methane CH 4 , and more complex processes such as the oxidation of glucose C 6 H 12 O 6 in the human body. The word oxidation originally implied reaction with oxygen to form an oxide, since dioxygen O 2 g was historically the first recognized oxidizing agent.
Later, the term was expanded to encompass oxygen-like substances that accomplished parallel chemical reactions. Ultimately, the meaning was generalized to include all processes involving loss of electrons. The word reduction originally referred to the loss in weight upon heating a metallic ore such as a metal oxide to extract the metal.

The antecedent to chapter provided an overview of the role that chemists can personally and professionally play in communication. The landscape study commissioned by the committee and performed by Grunwald Associates and the Education Maturity Center included.
Although not limited in scope and focus, the landscape about provides the best at one's disposal snapshot of current chemistry communication activities in the United States. This chapter draws heavily on the landscape study and contains many passages from the report. The landscape retreat uncovered a wide rank of communication events, conducted in a variety of settings for different participants.
These events include proficiency museums designing exhibits proper for all ages; university-based chemists engaging in lectures and community events; science journalism appearing in popular media print, radio, or tube ; entertainment media featuring chemistry e. The types of event format from traditional lectures and demonstrations to newer formats, such as flash mobs and science pubs. There also has been noticeable growth of chemistry communication on the Internet in the course videos, science blogs, podcasts, and social media.
Although it is impossible to discover and describe all chemistry communication activities, it is valuable to be aware of their dissimilitude. Given the goal of promoting a more regular design of these activities, it is useful to categorize them.

Did you ever hear advertising a food or a cosmetic as being "chemical-free"? How often a "natural" product is praised for its beneficial qualities, whereas a "chemical" origin is associated with certainly harmful properties? These examples clearly illustrate how mass media regularly counterfeit the meaning of the term "chemical" , using this word solely to imply hazard and aggressiveness.
This is the origin of several paradoxes typically present in advertisements and news! Water is "chemical" too, its formula is well known. Nevertheless, would a media man DARE to define water as a "chemical"? It is clear that " chemical " is confused with " synthetic ", implying that whenever a substance has been produced in a factory, an industry has polluted for its manufacture, and, hence, its composition can be harmful. Therefore, " chemical " becomes the negative counterpart of " natural ", ignoring that several substances produced in Nature are much more poisonous than those manufactured in the laboratory.
The lack of effective communication between chemistry and people is certainly also due to generally poor language skills of chemists, to their unwillingness to leave the lab and break into society, to a low ability to improve their professional image. Therefore, the social impact of other professionals, such as doctors, lawyers, engineers, architects, and the list can be longer, is much more brilliant than that of chemists.

Oxidation-Reduction Reactions , or redox reactions, are reactions in which one reactant is oxidized and a woman reactant is reduced simultaneously. This module demonstrates how to balance various redox equations. The firstly step in balancing any redox resistance is determining whether or not it is even an oxidation-reduction reaction, which requires that species exhibits changing oxidation states during the reaction.
To take care of charge neutrality in the sample, the redox reaction resolution entail both a reduction component and an oxidation components and is repeatedly separated into free two hypothetical half-reactions to aid in understanding the reprisal. This requires identifying which element is oxidized and which element is reduced.
