Which term refers to the process by which ions that have entered solution are kept in solution?


Adissociation
Belectrolyte
Chydration
Dionization

Verified Answer :

Final answer:

The process by which ions are kept in solution is known as hydration, where water molecules surround and stabilize the ions. This prevents the ions from recombining and allows them to remain dissolved. Dissociation, electrolyte, and ionization are related concepts but do not specifically refer to the stabilization of ions in solution.


Explanation:

Understanding the Process of Ions in Solution


The term that refers to the process by which ions that have entered a solution are kept in solution is hydration. When an ionic compound dissolves in water, the ions separate and interact with water molecules. This interaction is crucial because water molecules surround and stabilize the ions, preventing them from recombining and allowing them to remain in solution.


For example, when table salt (sodium chloride, NaCl) dissolves in water, the sodium ions (Na+) and chloride ions (Cl-) are surrounded by water molecules. The positive parts of the water molecules (hydrogen) attract the chloride ions, while the negative parts (oxygen) attract the sodium ions, leading to the process of hydration.


In contrast, dissociation refers to the process of breaking apart into ions, electrolyte describes a substance that conducts electricity when dissolved, and ionization generally refers to forming ions from neutral atoms or molecules. However, the specific process of keeping these ions in solution is best described by hydration.
