A solution is a fundamental concept in chemistry that plays a crucial role in various chemical reactions and processes. In this article, we will delve into the definition of a solution and determine whether the given statement is true or false.

What is a Solution?

A solution is a homogeneous mixture of two or more substances, where one substance (the solute) is dissolved in another substance (the solvent). The solute can be a solid, liquid, or gas, while the solvent is typically a liquid. The resulting mixture has a uniform composition and properties throughout.

Characteristics of a Solution

To determine if a mixture is a solution, we need to examine its characteristics. A solution must have the following properties:

Homogeneity: The mixture must have a uniform composition throughout.
No visible particles: The solute particles must be dispersed at a molecular or atomic level, making them invisible to the naked eye.
Ability to separate: The solute and solvent can be separated through physical means, such as evaporation or filtration.

Examples of Solutions

Some common examples of solutions include:

Water and sugar: When sugar is dissolved in water, it forms a homogeneous mixture.
Air: Air is a solution of gases, including nitrogen, oxygen, and carbon dioxide.
Saltwater: Seawater is a solution of salt (sodium chloride) in water.

Is the Statement True or False?

Now that we have a clear understanding of what a solution is, let's examine the given statement: "A solution is a homogeneous mixture of two or more substances."

Based on our discussion, we can conclude that the statement is TRUE. A solution is indeed a homogeneous mixture of two or more substances, where one substance is dissolved in another.

Conclusion

In conclusion, a solution is a fundamental concept in chemistry that plays a crucial role in various chemical reactions and processes. By understanding the characteristics and examples of solutions, we can determine whether a mixture is a solution or not. The given statement is true, and we can confidently say that a solution is a homogeneous mixture of two or more substances.

Key Takeaways

A solution is a homogeneous mixture of two or more substances.
A solution must have a uniform composition and properties throughout.
The solute and solvent can be separated through physical means.
Examples of solutions include water and sugar, air, and saltwater.

Q1: What is the difference between a solution and a mixture?

A: A solution is a homogeneous mixture of two or more substances, where one substance is dissolved in another. A mixture, on the other hand, can be either homogeneous or heterogeneous. In a heterogeneous mixture, the components are not uniformly distributed throughout the mixture.

Q2: What are the characteristics of a solution?

A: A solution must have the following characteristics:

Homogeneity: The mixture must have a uniform composition throughout.
No visible particles: The solute particles must be dispersed at a molecular or atomic level, making them invisible to the naked eye.
Ability to separate: The solute and solvent can be separated through physical means, such as evaporation or filtration.

Q3: What is the difference between a solute and a solvent?

A: The solute is the substance that is dissolved in the solvent. The solvent is the substance that does the dissolving. For example, in a solution of sugar and water, sugar is the solute and water is the solvent.

Q4: Can a solution be formed with a solid solute and a solid solvent?

A: Yes, a solution can be formed with a solid solute and a solid solvent. This type of solution is called a solid solution. An example of a solid solution is a mixture of iron and carbon, where the carbon is dissolved in the iron.

Q5: What is the difference between a saturated solution and an unsaturated solution?

A: A saturated solution is a solution that contains the maximum amount of solute that can be dissolved in the solvent at a given temperature. An unsaturated solution is a solution that contains less than the maximum amount of solute that can be dissolved in the solvent at a given temperature.

Q6: Can a solution be formed with a gas as the solute?

A: Yes, a solution can be formed with a gas as the solute. This type of solution is called a gas solution. An example of a gas solution is a mixture of oxygen and nitrogen in the air.

Q7: What is the difference between a solution and a colloid?

A: A solution is a homogeneous mixture of two or more substances, where one substance is dissolved in another. A colloid, on the other hand, is a mixture of two or more substances where one substance is dispersed in another, but not dissolved. An example of a colloid is a mixture of milk and water.

Q8: Can a solution be formed with a liquid solute and a liquid solvent?

A: Yes, a solution can be formed with a liquid solute and a liquid solvent. This type of solution is called a liquid solution. An example of a liquid solution is a mixture of ethanol and water.

Q9: What is the difference between a solution and a suspension?

A: A solution is a homogeneous mixture of two or more substances, where one substance is dissolved in another. A suspension, on the other hand, is a mixture of two or more substances where one substance is dispersed in another, but not dissolved. An example of a suspension is a mixture of sand and water.

Q10: Can a solution be formed with a solid solute and a gas solvent?

A: Yes, a solution can be formed with a solid solute and a gas solvent. This type of solution is called a solid-gas solution. An example of a solid-gas solution is a mixture of carbon dioxide and dry ice.
