Question

Oxidation is the ________ and reduction is the ________. Oxidation is the ________ and reduction is the ________. gain of electrons, loss of electrons loss of oxygen, gain of electrons gain of oxygen, loss of mass gain of oxygen, loss of electrons loss of electrons, gain of electrons

Answer 1

Oxidation is the loss of electrons and reduction is the gaining of electrons.

Step-by-step explanation:

Given the following reaction:

Na + Cl→ NaCl

For the reaction to occur Na has to give up an electron meaning it losses an electron as shown:

Na→Na+ + e-

on the other hand, chlorine gains an electron as shown:

Cl- + e- → Cl

This implies that Na is being oxidized while Chlorine is reduced.

The two ions(Na+ and Cl-) then combine to form Sodium Chloride.

Answer 2

Oxidation is the loss of electrons and reduction is the gain of electrons

Step-by-step explanation:

• Oxidation involves the loss of electrons by an atom of an element. For example, an atom of copper undergoes oxidation by losing two electrons.

Cu(s) → Cu²⁺(aq) + 2e

• Oxidation may also refer to an increase in the oxidation number of an element. In the above example, the oxidation number of Cu is 0 while that of Cu²⁺ is +2.
• Reduction involves the gain of electrons by an atom of an element.
• For example, an atom Oxygen undergoes reduction by gaining two electrons.

O + 2e → O²⁻

• The reduction also occurs when the oxidation number of an element decreases. In this case, the oxidation number of oxygen decreases from 0 to -2.
