Redox chemical reaction
In any redox reaction, the total number of electrons lost must equal the total of electrons gained to preserve electrical neutrality. In Equation 4.5.3, for example, the total number of electrons lost by aluminum is equal to the total number gained by oxygen: electrons lost = 4Alatoms × 3e − lost Alatom = 12e − lost.A redox reaction is a chemical reaction in which the atoms change their oxidation numbers. Some atoms lose electrons and are oxidized - a process known as oxidation. On the other hand, some atoms gain electrons and are reduced - a process known as reduction. Therefore, both REDuction and OXidation take place simultaneously, hence the term ...A redox reaction is a chemical reaction that involves the transfer of electrons between chemical species. A reduction involves gaining electrons, while an oxidation involves losing electrons. In a redox reaction, electrons are transferred from one species to another. One species is oxidized and loses electrons, which then are accepted by the ...
