Answer:

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

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:

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

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.
