Question

what is Oxidation and reduction reaction ​

Answer 1

Answer:

Oxidation Definition

Oxidation is the loss of electrons during a reaction by a molecule, atom or ion.

Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases.

An example of a reaction is that between hydrogen and fluorine gas to form hydrofluoric acid:

H2 + F2 → 2 HF

In this reaction, hydrogen is being oxidized and fluorine is being reduced. The reaction may be better understood if it is written in terms of two half-reactions.

H2 → 2 H+ + 2 e-

F2 + 2 e- → 2 F-

Note there is no oxygen anywhere in this reaction!

Answer 2

Oxidation and Reduction Or Redox reaction

=》 The reaction in which one substance get oxidised and another get reduced is called redox or oxidation reaction.

● What is Oxidation?

=》 It is a process in which a substance gains oxygen or loses hydrogen is called oxidation.

If substance gains oxygen it is said to be oxidized.

● What is Reduction ?

=》 It is a process in which a substance gain hydrogen or loses oxygen is called reduction reaction.

If a substance loses oxygen or gains hydrogen it is said to be reduced.
