The true solution is a fundamental term that is a homogeneous mixture where two or more solutions are mixed to form a single new solution. Further, there are several properties of a true solution that makes it different from colloidal solutions and suspensions. This article talks about the properties of a true solution. You will find brief information on the concept of true solutions in chemistry, a thorough explanation of properties of a true solution, examples of true solutions, and so on.

Concept of the true solution 

The true solution is a homogeneous mixture that consists of two or more substances. Here the solute is completely dissolved in the solvent forming a liquified and transparent solution. The mix of sugar or salt in water is one of the most popular examples of a true solution. It is a homogeneous mixture in which any solute and solvent particles do not settle down at the bottom of the true solution. Through this state, the light passes conveniently without scattering.

The size of the particles in the true solution is less than 1 nm which also means that it is hard to view particles through naked eyes. True solutions are hard for filtration or separation procedures as the solvent and solution get a dissolved state completely. Here the density of the particles is relatively high as the amount of the particles in the solution is equal in unit per volume. The effect of Brownian and Tyndall is not present in this solution.

Properties of the true solution 

The following are the properties of a true solution – 

• The true solution is the homogeneous mixture. 
• The true solution is completely transparent or colourless. 
• The true solution has solute particles that do not dissolve when mixed with water or other liquids. 
• The true solution does not scatter light as the particles are nearly non-existable in size. 
• The size of the true solution particles is about 10-10 m only. 
• The solute particles are extremely small and have a diameter of less than 1 nm. 
• Owing to its small size, its particles cannot be seen through the naked eyes or a microscope. 
• The solution particles can easily pass through the filter paper, making it nearly impossible to separate the solution. 
• If kept untouched, the particles do not settle down. 

Types of the true solution 

There are different types of true solutions based on various factors. Below, we have curated types of solutions based on different criteria for your ease of understanding. Here we go! 

1- Based on the water as a solvent 

• Aqueous solutions 
• Non-aqueous solutions 

2- Based on the amount of solute added

• Unsaturated solution 
• Saturated solution 
• Supersaturated solution 

3- Based on solvent added 

• Concentrated solution 
• Dilute solution

4- Based on solute concentration in two solutions 

• Isotonic solution 
• Hypertonic solution 
• Hypotonic solution 

Examples of true solutions 

Conclusion 

With this, we come to an end to the properties of true solutions. It is the homogeneous mixture of two or more substances. Here the solute is completely dissolved in the solvent forming a liquified and transparent solution. A typical example of a true solution is the mix of sugar or salt in water. Solutions have different properties that we discussed in this article. 

In this article describing the properties of true solutions, we studied the concept of the solution in length. We covered several other topics, such as a thorough explanation of solutions, differences between their types, properties of a true solution, and so on.
