distinction between true solutions

True solutions are homogeneous mixtures of two or more compounds, whereas colloidal solutions and suspensions are heterogeneous combinations of two or more substances. Another difference between these three types of solutions is that the true one is transparent, whereas the colloidal is translucent and the suspension is opaque.

For the purposes of chemical definition, solutions are defined as a mixture of two or more substances in which a solvent is present in liquid form and a solute is present in any of the three states of matter (liquid, solid or gas). There are many various types of solutions, each with its own set of characteristics, however, they may be broadly classified as true solutions, colloidal solutions or suspension solutions.

Those solutions may be classified based on particle size, solution type, diffusion, sedimentation ability and so on. Brownian motion and the Tyndall effect also distinguish them (solutions).

Brownian motion refers to the random motions or motion of particles in a solution as a result of collisions. The Tyndall effect, on the other hand, is the outcome of a beam of light passing through a liquid, with the particles present in the liquid producing varied results.

In this article, we’ll look at the differences between the three sorts of solutions, as well as a summary of them.

Definition of True Solution

True solution is a homogeneous combination of two or more substances in which the solute is dissolved in the solvent. The particles are less than 1 nm in size in this case. When sugar or salt is dissolved in water, this is an example of a real solution. Filter paper or parchment paper will not be able to filter or separate the particles. The particles themselves are undetectable to the human eye.

Because the solution is in the liquid phase and clear, light may flow through it without being dispersed. When a solution is described as homogeneous, it indicates that the particles are spread uniformly throughout the solution and do not sink to the bottom of the container. The particle density is larger because the number of particles per unit volume of the solution is the same everywhere.

In a true solution, light must not disperse. Filtration would be unable to discriminate between the constituents of a true solution. The Brownian effect, as well as the Tyndall effect, are not detected in real solutions.

Definition of Colloidal Solution

A colloidal solution is a heterogeneous combination of two or more substances with particle sizes ranging from 1 to 1000 nanometers. Colloidal solution is a mixture of true solution and suspension, albeit it is still in the liquid phase. Colloidal solutions are made up of microscopic particles that float instead of being dissolved, such as starch dissolved in water or gelatin combined in water.

Similarly to the actual solution, the colloidal solution particles are invisible to the naked eye but may be seen using an electron microscope.

The separation of colloidal particles may be accomplished using parchment paper, but not using filter paper. The particles can be obtained using a centrifugation procedure, in which they (particles) settle to the bottom. The particles in the solutions are not equally distributed due to the heterogeneous nature of the combination.

Because colloidal solutions are transparent, they enable light to flow through the liquid, but the light is dispersed due to the presence of particles. Colloidal solution exhibits Brownian motion and the Tyndall effect. Reversible or irreversible emulsion, foam, sol, hydrocolloid colloids come in a variety of shapes and sizes.

Definition of Suspension

Suspensions are mixtures in which the particle size is greater than 1000 nm. When dirt is dissolved in water that is vigorously churned, the particles of the solution settle at the bottom of the container after a period of time due to gravity; this is an example of suspension.

The particles in the real solution can be seen with the naked eye. Suspension exhibits Brownian motion and the Tyndall effect.

Conclusion

The solution is defined in chemistry as a combination of two miscible or immiscible compounds in a liquid or gas media. In this article, we discussed the three sorts of solutions, their qualities and how they differ.
