Difference Between Mixture And Solution

A mixture is a combination of two or more substances in which each substance just mixes together and no new compound is formed retains its individual characteristics and properties. E.g. sugar crystals being mixed with salt grains, sand, dissolved in water, etc. while a solution is a homogenous mixture formed by a substance dissolved into another substance. E.g. sugar dissolved in water or salt dissolved in water etc. the basic Difference Between Mixture And Solution is that in the mixture, the composition of elements is not fixed. on the other hand, a solution contains two substances that are chemically mixed to form a new compound.

Difference Between Mixture And Solution in tabular Form

Mixture Solution
mixtures are those in which substances are only mixed together but not dissolved. on the other hand, solutions are those in which different substances are not only mixed together but dissolved completely.
they are formed when two or more compounds are mixed in this manner that they are not chemically fused together. these compounds also have no physical interactions. they are formed with those substances that are chemically mixed and completely fused with each other to make a new compound.
without bringing change in their chemical properties, they retain their original properties. they bring change in their chemical properties, and cannot retain their original properties.
the number of substances taking part to make a mixture can vary and do not have a fixed value. it has a fixed ratio of the number of pure substances taking part in it.
they are of two types i.e. homogeneous mixtures and heterogeneous mixtures. only homogeneous mixtures can be a solution.

 

What is a Mixture?

A mixture in chemistry, forms when two or more substances are mixed or combined together such that each substance retains its own chemical identity. The Chemical bonds are neither broken nor formed between the components. Note that the chemical properties of the components have not changed.

it may exhibit new physical properties i.e. boiling and melting point. Note that mixture formation never involves any chemical reaction and chemical properties maintain its chemical identity participating components in a mixture.

For example, a mixture of water and alcohol has a higher boiling point and lower melting point than alcohol. Examples of mixtures include combinations of salt and sand, sugar and water, and blood.

Types of Mixture

Mixtures are divided into two broad categories are heterogeneous and homogeneous mixtures. Heterogeneous mixtures are not uniform throughout the composition (e.g. gravel), while homogeneous mixtures have the same phase and composition.

The distinction between Homogeneous and heterogeneous mixtures is a matter of magnification or scale. E.g. even air can appear to be a heterogeneous mixture, if the sample only contains a few molecules, while a bag of mixed vegetables may appear homogeneous if your sample is an entire truckload full of them.

Also note, even if a sample consists of a single element, it may form a heterogeneous mixture. One example would be a mixture of pencil lead and diamonds (both carbon). Another example could be a mixture of gold powder and nuggets. According to the particle size of the components, the mixtures may also be described.

What is a Solution?

It is a homogeneous mixture of two or more substances or a chemical solution is a solution that consists of small particle sizes (less than 1 nanometer in diameter). A solution may exist in any phase. It is physically stable and the components may not be separated by decanting or centrifuging the sample.

It consists of a solute and solvent. The solute is the amount dissolved in a solvent. Solubility is the amount of solute that is dissolved in the solvent. E.g. in a saline solution, salt is the amount of solute dissolved in water as the solvent. Particles in a solution are not visible to the naked eye.

A solution does not scatter a light beam. A solution is composed of one phase (solid, liquid, gas). Air (gas), dissolved oxygen in water (liquid), opal (solid), and mercury in gold amalgam (solid), and gelatin (solid) are examples of solutions.
