Overview of Solute and Solvent
Have you ever wondered why is it always said to mix sugar or salt in water? Why can’t you mix one tablespoon of water with a glass of sugar? What will happen then? So, this is about solute and solvent which make a solution on mixing.
In this article, we will learn what is solute and solvent and also discover some solute and solvent examples. Let's dive into the article to understand this topic better and start with a solution. The solution is something that is made by mixing solute and solvent. Let’s start with some more scientific definition of it.
Solute and Solvent
What is a Solution?
A uniform mixture of solutes dissolved in a solvent is a solution. A mixture of two or more components with a uniform appearance and composition is referred to as a homogeneous solution. If one tablespoon of sugar is mixed with one glass of water, then it makes a homogeneous mixture having sugar as solute and water as solvent.

Examples of Solution
Here are a few examples of solutions.
Seawater (Solid in Liquid)
Vinegar (Liquid in Liquid)
Carbonated Drinks (Gas in Liquid)
Air (Gas in Gas)
What is Solute?
The component dissolved in a fluid to form a solution is known as a solute. The solute concentration is a deciding factor in determining whether the solution is solid, liquid, or gaseous.
Examples of Solute
Listed below are a few examples of solutes.
Almost all metallic salts
Sugar
Edible Salt
What is a Solvent?
A solvent is usually a liquid that is used to dissolve a solute. It is a liquid that dissolves other components to generate a solution. Now, ion production is favoured by polar solvents like water but not by nonpolar solvents like hydrocarbons. Water is a good example of a solvent.
Classification of Solvents
Solvents can be classified into Polar (example water) and Non-Polar (example, hydrocarbons) solvents.
Polar and Non-Polar Solvents
Ion formation is aided by polar liquids. Ions do not form in non-polar liquids. The dielectric constant describes a solvent's ability to generate ions. Water has a relatively high dielectric constant. Due to water's high dielectric constant, compounds with ionic bonds will tend to dissociate in water, resulting in ion-containing solutions.
Examples of Solute in Solvent
The following are a few examples of solutes and solvents.
Sugar and water (sugar solution)
Salt and water (salt solution)
Sand and water (sand solution)
Difference Between Solute and Solvent
Solute, Solvent and Solution
The difference between solute and solvent can be determined based on their definition, physical appearance (basically a state of matter:- solid, liquid, or gas form), solubility, and boiling point. Let us see how!
Firstly have a look at the definition of physical state, solubility and boiling point for better understanding.
Physical State: Physical state refers to the state that defines a substance's shape (gas, liquid, or solid) at a given temperature and pressure. The solute can be solid, liquid or gas, but solvents are mostly liquid; only some are gas or solid.
Solubility: The ability of a certain material, the solute, to dissolve in a solvent is referred to as solubility. Solubility of solute is determined by its surface area and molecular size, whereas solubility of solvent is determined by its polarity.
Boiling point: The boiling point for any material is the temperature point at which the material transforms into the gas phase from the liquid phase. The boiling point of the solute is higher, but the boiling point of the solvent is lower.
The difference between solute and solvent is given below:
Summary
It is the solvent's role to dissolve the solute, not the other way around. Solutions can be made with a huge variety of solutes and solvents. A mixture of two or more dissolved compounds in a liquid medium is a solution. To distinguish them from heterogeneous mixtures (many compounds exist in various configurations), solutions are homogeneous, which means that the atoms of the solute are evenly dispersed throughout the solvent (e.g., water, ethanol). We are aware of a wide range of solutions discussed in the article.

FAQs on Solute and Solvent
1. What are solutes and solvents in a solution?
A solution is a uniform mixture of two or more substances. The substance that gets dissolved is called the solute. The substance that does the dissolving, and is usually present in a larger amount, is called the solvent. For example, when you mix salt in water, salt is the solute and water is the solvent.
2. What is the main difference between a solute and a solvent?
The main difference lies in their role and quantity in a solution. The solute is the substance that is dissolved and is usually the component in a smaller amount. The solvent is the substance that does the dissolving and is typically the component in a larger amount.
3. Can you give some common examples of solutes and solvents?
Certainly. Here are a few everyday examples of solutions:
- In saltwater, salt is the solute and water is the solvent.
- In fizzy drinks, carbon dioxide gas and sugar are solutes dissolved in water, which is the solvent.
- In the air, nitrogen is the main solvent, and other gases like oxygen are solutes.
- Brass is a solid solution where zinc (solute) is dissolved in copper (solvent).
4. Why is water often called the 'universal solvent'?
Water is called the 'universal solvent' because it can dissolve more substances than any other common liquid. This powerful dissolving ability comes from the polarity of its molecules, which can attract and separate the particles of many different solutes, including salts, sugars, and acids.
5. Can a solvent be something other than a liquid?
Yes, absolutely. While liquid solutions are most common, solutions can exist in any state of matter. For example, air is a gaseous solution where nitrogen acts as the solvent. Alloys like steel or brass are solid solutions where one metal is dissolved in another.
6. What happens if you add too much solute to a solvent?
If you keep adding solute to a solvent, you will eventually reach a point where no more can dissolve. This is called the saturation point, and the solution becomes a saturated solution. Any additional solute added after this point will not dissolve and will remain separate, often settling at the bottom.
7. In a glass of milk, what acts as the solute and what as the solvent?
Milk is a complex mixture, but in simple terms, water is the main solvent as it makes up the largest part. The solutes are the various substances dissolved or suspended in the water, such as lactose (milk sugar), proteins, vitamins, and minerals.
