What is redox in chemistry.
Electrochemistry Basics. Electrochemistry is the study of chemical processes that cause electrons to move. This movement of electrons is called electricity, which can be generated by movements of electrons from one element to another in a reaction known as an oxidation-reduction ("redox") reaction.
Key Takeaway. Chemical reactions in which electrons are transferred are called oxidation-reduction, or redox, reactions. Oxidation is the loss of electrons. Reduction is the gain of electrons. Oxidation and reduction always occur together, even though they can be written as separate chemical equations.Redox chemistry plays an enormous part in our daily lives in today’s electronic world, particularly in the use of smartphones, which rely on the latest redox cell technology. The voltage of a cell or battery depends on several factors, including what the electrodes are made from and the substance used as the electrolyte.reduction, any of a class of chemical reactions in which the number of electrons associated with an atom or a group of atoms is increased. The electrons taken up by the substance reduced are supplied by another substance, which is thereby oxidized.

The electrons taken up by the substance reduced are supplied by another substance, which is thereby oxidized. See oxidation-reduction reaction.a) The appropriate oxidation numbers are. The only atoms which change are Mn, from +7 to +2, a reduction, and S, from +4 to +6, an oxidation. The reaction is a redox process. SO 2 has been oxidized by MnO 4–, and so MnO 4– is the oxidizing agent. MnO 4– has been reduced by SO 2, and so SO 2 is the reducing agent. b) The oxidation numbers.Redox potential, also known as standard electrode potential, is a measure of how easily a substance loses or gains electrons in a reduction- oxidation — or “redox” — reaction, a chemical reaction where one reactant is reduced and the other oxidized. Electrons move from the reducing agent to the oxidizing agent.
