Difference Between Mixture and Solution


Main Difference

The main difference between Mixture and Solution is that Mixture is a combination of two substances that aren’t chemically dissolved, whereas Solution is a mixture of two dissolved substances.

Mixture vs. Solution

In mixture amount of added substances is not have a fixed ratio. In solution substances of the same ratio are to be added. A mixture can be homogenous or heterogeneous. However, a solution is always a homogeneous mixture. After mixing the substances in the mixture, their chemical properties are still the same. Chemical properties of substances in the solution are getting changed after mixing.

The mixture can exist in 3 states of matter. The solution only exists in one state in liquid form. Components are intermingling in the mixture without chemical bonding. Components are mixing by making chemical bonds. Mixtures are easy to separate with the help of any type of thermal and mechanical method. Solutions are hard to separate by different methods.


There is no proper molecular interaction among mixture substances. However, there is a proper interaction of molecules of a substance in case of a solution. In mixture, the mixing of substances is not regulated by any specification. The mixing of the solution is regulated by specific chemical polarity and concentration. It is noticed that physical properties such as melting point etc. of substances are highly affected in the mixture. There is no drastic change in the physical properties of substances in solution.

Substances are not thoroughly mixed in the mixture. Substances are evenly mixed in solution. A mixture is just an act of mixing. As well as the solution is a state of being dissolved. The mixture doesn’t possess fixed melting points. The solution possesses specific and fixed melting points.

What is a Mixture?

In the definition of chemistry mixture is a matter that is the constituent of two or more different kinds of substances. These mixed substances are responsible for the physical combination. These two or more elements are which are being mixed in the form of a solution, colloids, and suspension. In mixtures, compounds are mechanically blended instead of making chemical bonds or any chemical change. It means that all the constituents in the mixture have their unchanged chemical properties.

Physical properties of Ingredients of a mixture such as melting points become change slightly from the original component. Mixed ingredients can also be separated from each other, utilizing thermal and mechanical processes. Some mixtures are difficult to separate like azeotropes mixtures. Components are not blended in a mixture; neither gets the bounded together, nor does it result in a new substance. For instance, a mixture of water and sand both ingredients are not chemically indulged and can easily get separate by the process of filtration.

There are also some other means of separating components like evaporation, centrifugation, distillation, extraction, chromatography, etc. To do such separation, some physical properties of substances like size, density, and solubility are strongly considered. Mixtures don’t possess their properties. However,


  • Homogenous Mixture: Homogeneous mixture has a fixed composition throughout the mixture. For example, salt in water.
  • Heterogeneous Mixture: The composition of the heterogeneous mixture varies from point to point in the mixture. For example, the Blue Ocean and air through which we breathe are also a heterogeneous mixture.

What is a Solution?

The solution is a homogenous mixture of two or more same kind of substances. When one of the substances is solvent or water, then this solution is known as “aqueous solution.” In aqueous solution, one substance is solute, and the other is solvent, the solute is getting dissolved in the solvent. Substances are mix in the solution resulting in an interaction between the molecules due to the effect of chemical polarity. If the solvent in the mixture is in a large fraction, then it is said that the solution is itself a solvent in that case. The concentration of solute in any solution can always be expressed in terms of the percentage of the whole mass solution.

In a solution, the important part is always the solvent, and it is abundantly present in the solution. However, the solute is just a substance to be dissolved in any solution. Usually, the size of the solute particles is about less than 1nanometer (nm). These particles of solute are either at the molecular level or atomic level. Solute and solvent particles are blend together and making bonds and other interactions, so that’s why it is difficult to be distinguished even under the microscope. When a solute and a solvent are gently and evenly distributed together, they create a specific homogeneity.

That’s the reason it is difficult to separate the ingredients of a solution. For instance, Sodium Chloride is solid when it is dissolved in water; it becomes transparent. Usually, solutions are transparent because the size of solute particles is much small, and it resists the reflection of light.

Key Differences

  1. A mixture is to or more kind of substances mixture, whereas a solution is only one kind of substance mixture.
  2. The mixture is not throughout a uniform mixture; on the other hand, the solution is throughout a uniform mixture.
  3. In mixture substances are getting mixed; conversely, in solution, substances are dissolved completely.
  4. Substances of the mixture are solid or liquid; on the flip side, the solution has solute and solvent as substances.
  5. The mixture can be solid, gas, or liquid, while the solution is always liquid.
  6. The ingredients of the mixture can be separated, although the ingredients of the solution can’t be separated.
  7. The mixture is the unification of substances as compared to a solution that involves dissolving.
  8. Substance particles are loosely bonded in the mixture, comparatively to the particles of the substance of solution.
  9. A mixture doesn’t disturb the chemical properties of the substance. However, the solution changes the chemical properties of mixing substances.
  10. In mixture, substance particles are just physically bonded; on the other side, in solution substance particles are chemically bonded.


It is concluded that the mixture is about different substances, and the solution is about similar substances.
