Solute – Definition and Examples


A solute is defined as the dissolved substance in a solution. The solvent is present in greater quantities than the solution for fluid solutions.

Thus, concentration is a measurement of the quantity of a solvent present in a chemical solution.

Definition of Solute in Chemistry

A solute is a substance that a solvent can dissolve to create a solution. Further, a the solution can come in many ways. It can be either oil, water, or heavy.

Moreover, the water, the material that dissolves the liquid, splits apart the solvent and evenly distributes the solvent molecules. Thus, this creates an all-round homogeneous mixture or solution.


Solutes are measured by concentration in solution. Similarly, a solution concentration is the amount of solution divided by the total solution volume.

Further, the solvent will dilute different amounts of solvent-based on how strong a solvent is used and how quickly the solvent molecules disintegrate. Thus, this solute dissolving property in a solvent is solubility.

Examples of Solute

Salt in Water

You create a solution when you dump a salt-filled spoon into a glass of water. Similarly, the salt, or NaCl, is the solution. Air, or H2O, is the solution.

The molecules of water are charged negatively on the atoms of oxygen. Similarly, they are charged positively on the atoms of hydrogen.

Salt is an ionic compound made up of two ions: Na+ and Cl–. Negative atoms of oxygen attract positive sodium (Na+), and positive atoms of hydrogen attract negative atoms of chlorine (Cl–).

Moreover, the attraction between the various molecules at a molecular level pulls the solvent apart and suspends it evenly throughout the water.

Further, the surface area of the solution which exposes is an important factor in how quickly the solution will dissolve. When we use coarse salt, there is less contact with the surface area.

Further, it will take longer to absorb the same amount of salt. A finer salt allows many more ions to expose to water and faster diffusion of the solute through the water.

Ultimately, the salt can is longer on the glass bottom because it distributes evenly throughout the glass.

Oxygen in Solute

Oxygen is an example of a gaseous solvent. From the strange creatures in the deepest parts of the ocean to the common coral-dwelling fish that scuba divers love, every fish in the ocean relies on oxygen dissolved in the water to live.

The oxygen that exists as O2 is a molecule of polarity. As such, the molecules of polar water tend to attract oxygen naturally. The hydrogen absorbs into the liquid as the waters push moisture into the sea and the ocean surface and environment connect.

The absorption cycle brings oxygen through the water column, supplying nutrients across the sea to the creatures.
In some situations, oxygen in the water uses up faster by the organisms in the ocean than it can be spread into the water.

This can happen when people run into the ocean with excess nutrient runoff. The nutrients, which are another water solute, permit the production of tremendous algal blooms.

There are far too many algae in these blooms. The algae in the lower layers begin to die, and then bacteria start consuming it.

Most hydrogen uses up between the coral and the bacteria. This creates a dead zone in the column of water. When fish attempt to swim through this pillar, the lack of oxygen can suffocate them.
