Ionization is a fundamental process in chemistry that involves the formation of ions from neutral molecules or atoms. It is a crucial concept in understanding various chemical reactions and phenomena. In this article, we will explore the concept of ionization and identify an example of this process from the given options.

What is Ionization?

Ionization is the process by which a neutral molecule or atom gains or loses electrons to form ions. This process can occur through various mechanisms, including the absorption of energy, such as light or heat, or through chemical reactions. Ionization can result in the formation of cations (positively charged ions) or anions (negatively charged ions).

Types of Ionization

There are several types of ionization, including:

Electron ionization: This type of ionization occurs when an electron is removed from a neutral molecule or atom, resulting in the formation of a cation.
Proton ionization: This type of ionization occurs when a proton is removed from a neutral molecule or atom, resulting in the formation of an anion.
Photoionization: This type of ionization occurs when a molecule or atom absorbs light energy, resulting in the ejection of an electron.

Examples of Ionization

Now that we have a basic understanding of ionization, let's examine the given options to identify an example of this process.

Option A: $ C + O_2 \rightarrow CO_2 $

This reaction involves the combination of carbon (C) and oxygen (O2) to form carbon dioxide (CO2). While this reaction involves the formation of a new compound, it does not involve the ionization of any species.

Option B: $ H_2CO_3 \rightarrow H_2O + CO_2 $

This reaction involves the decomposition of carbonic acid (H2CO3) into water (H2O) and carbon dioxide (CO2). While this reaction involves the formation of new compounds, it does not involve the ionization of any species.

Option C: $ SO_2 + H_2O \rightarrow HSO_3^{-} + H^{+} $

This reaction involves the reaction of sulfur dioxide (SO2) with water (H2O) to form sulfurous acid (HSO3-). However, this reaction does not involve the ionization of any species, as the sulfurous acid is still a neutral molecule.

Option D: $ Mg(OH)_2 \rightarrow Mg^{2+} + 2OH^{-} $

This reaction involves the decomposition of magnesium hydroxide (Mg(OH)2) into magnesium ions (Mg2+) and hydroxide ions (OH-). This reaction is an example of ionization, as the magnesium hydroxide molecule is broken down into ions.

Conclusion

In conclusion, the correct answer is Option D: $ Mg(OH)_2 \rightarrow Mg^{2+} + 2OH^{-} $. This reaction is an example of ionization, as the magnesium hydroxide molecule is broken down into ions. Understanding ionization is crucial in chemistry, as it is a fundamental process that occurs in various chemical reactions and phenomena.
