What Is True Solution?

Are you curious to know what is code true solution? You have come to the right place as I am going to tell you everything about code true solution in a very simple explanation. Without further discussion let’s begin to know what is code true solution?

In the realm of chemistry, a true solution is a fundamental concept that underlines the homogeneity of certain mixtures. This article aims to provide a comprehensive understanding of what constitutes a true solution, exploring its definition, examples, properties, and its significance in various academic levels.

What Is True Solution?

A true solution in chemistry refers to a homogeneous mixture where solute particles are molecular-sized and evenly dispersed in the solvent. This even distribution results in a transparent and stable solution, showcasing the absence of visible particles.

What Is True Solution Example?

An exemplary example of a true solution is salt dissolved in water. When common table salt (NaCl) dissolves in water, the resulting solution is clear, demonstrating the characteristics of a true solution.

What Is True Solution Class 9:

For students in Class 9, the concept of true solutions introduces the idea of homogeneous mixtures, laying the groundwork for more advanced studies in chemistry. Understanding the molecular-level nature of true solutions sets the stage for more intricate topics in later classes.

What Is True Solution Class 12:

In Class 12, the study of true solutions delves deeper into the intricacies of their composition and behavior. Students explore the thermodynamics and kinetics associated with the dissolution process, gaining a more profound understanding of true solutions.

Properties Of True Solution:

  • Homogeneity:

True solutions exhibit uniform composition, ensuring that the solute is evenly distributed in the solvent.

  • Stability:

True solutions remain stable over time, showing no signs of separation or settling.

  • Transparency:

True solutions are typically transparent, allowing light to pass through without scattering.

  • Particle Size:

The particles in a true solution are molecular-sized, generally less than 1 nanometer in diameter.

  • No Tyndall Effect:

Unlike colloids, true solutions do not exhibit the Tyndall effect, which is the scattering of light by larger particles.

10 Examples Of True Solution:

  • Salt in Water (NaCl):

Common table salt dissolved in water.

  • Sugar in Water (Sucrose):

Granulated sugar dissolved in water.

  • Alcohol in Water (Ethanol):

Ethanol completely mixing with water to form a true solution.

  • Oxygen in Water (O2):

Molecular oxygen dissolving in water.

  • Carbon Dioxide in Water (CO2):

Carbon dioxide dissolving in water to form carbonic acid.

  • Glucose in Water:

Glucose molecules dispersing uniformly in water.

  • Hydrochloric Acid in Water (HCl):

Hydrochloric acid fully dissolving in water.

  • Ammonium Chloride in Water (NH4Cl):

Ammonium chloride forming a clear solution in water.

  • Sodium Hydroxide in Water (NaOH):

Sodium hydroxide undergoing complete dissolution in water.

  • Nitric Acid in Water (HNO3):

Nitric acid dissolving seamlessly in water.

Is Milk A True Solution?

Milk is not a true solution but rather a colloid. It contains larger particles like fat globules and casein proteins, leading to the scattering of light, a phenomenon known as the Tyndall effect.

True Solution Is Also Known As:

A true solution is also known as a molecular solution. This nomenclature highlights the fact that the solute particles exist at the molecular level, contributing to the homogeneity of the mixture.


In conclusion, understanding what a true solution is in chemistry is foundational to grasping the intricacies of mixtures and their behavior at the molecular level. From the molecular-sized particles to the transparent and stable nature of true solutions, this concept plays a crucial role in various academic levels. Whether introduced in Class 9 or explored in greater depth in Class 12, the knowledge of true solutions sets the stage for more advanced studies in the fascinating world of chemistry.


What Is A True Solution Called?

A homogeneous solution that is stable and formed as a result of the complete dissolution of the solute in the solvent is called a true solution. Examples: Air, vinegar, sugar solution, etc. Was this answer helpful? 0.

What Is A True Solution Class 9th?

True Solution is a homogeneous mixture of two or more substances in which substance dissolved (solute) in solvent has the particle size of less than 10-9 m or 1 nm. Simple solution of sugar in water is an example of true solution.

What Are The Three Characteristics Of A True Solution?

A true solution is a homogeneous mixture. A true solution does not scatter light. A true solution is clear and transparent. The solute particles in a true solution do not settle down.

What Are Two True Solutions Examples?

Several examples of true solutions are there in nature as well as in our daily life, such as simple sugar in water, salt in water, air, acetic acid in water, ethanol in water, lemon juice, etc.
