Question

What is a redox reaction?

Answer 1

A redox reaction consist of 2 processes to be considered 1:
A oxidation reaction: a reaction in which a chemical lose electrons.
A reduction reaction: a reaction in which a chemical obtain electrons.

Answer 2

We usually put a redox equation on this form:
Red(1) + Ox(2) -> Ox(1) + Red(2)

Answer 3

Redox (reduction-oxidation) reactions include all chemical reactions in which atoms have their oxidation state changed—that is, redox reactions involve the transfer of electrons between species.

Answer 4

Redox reaction means reduction and oxidation reaction. When a reduction and oxidation reaction takes place in the reaction vessel then redox reaction has occurred.

Answer 5

Redox (reduction-oxidation) reactions include all chemical reactions in which atoms have their oxidation state changed—that is, redox reactions involve the transfer of electrons between species.
This can be either a simple redox process, such as the oxidation of carbon to yield carbon dioxide (CO
2) or the reduction of carbon by hydrogen to yield methane (CH4), or a complex process such as the oxidation of glucose (C6H12O6) in the human body through a series of complex electron transfer processes.
The term "redox" comes from two concepts involved with electron transfer: reduction and oxidation.[1] It can be explained in simple terms:
Oxidation is the loss of electrons or an increase in oxidation state by a molecule, atom, or ion.
Reduction is the gain of electrons or a decrease in oxidation state by a molecule, atom, or ion.
