Solute, Solvent and Solution | Chemistry
TLDRThis video script introduces the concepts of solute, solvent, and solution with illustrative examples. It explains that a solution is a homogeneous mixture where the solute is the substance present in a smaller amount, and the solvent is the one in a larger amount. Common examples of solutions include soft drinks, clouds, smoke, and alcohol mixed with water. The video also highlights water's unique property as a 'universal solvent' due to its ability to dissolve many polar substances, but not non-polar ones.
Takeaways
- 📚 A solution is a homogeneous mixture of two or more substances, characterized by a uniform composition.
- 🧂 Salt dissolves in water to form a homogeneous mixture, making it soluble and resulting in a solution.
- 🍬 Sugar also dissolves in water, creating a homogeneous mixture and is considered a solution as well.
- 🌑 Pebbles or sand do not dissolve in water, leading to a heterogeneous mixture, which is not a solution.
- 🥤 Examples of solutions include cold drinks, where carbon dioxide, sugar, and flavors are dissolved in water, and clouds, where water vapors are in the air.
- 🌫 Smoke in the air is a solution of carbon particles dissolved in the air, and alcohol in water is a solution with alcohol as the solute and water as the solvent.
- 🧪 Solute is the substance present in a solution in a smaller amount, while the solvent is the substance present in a larger amount.
- 🍶 In a vinegar solution, acetic acid is the solute and water is the solvent.
- 🥛 In milk, sugar dissolved forms a solution where sugar is the solute and milk is the solvent.
- 🌬️ Air is the solvent for carbon particles in smoke, making it a solution.
- 💧 Water is known as the universal solvent due to its ability to dissolve many polar substances, but it cannot dissolve non-polar substances.
Q & A
What is a solution?
-A solution is a homogeneous mixture of two or more substances where one substance is dissolved in another.
How can you identify if a substance is soluble in water?
-A substance is considered soluble in water if it completely dissolves, forming a uniform composition that cannot be distinguished by the naked eye.
What is the difference between a solute and a solvent?
-The solute is the substance present in a smaller amount in a solution, while the solvent is the substance present in a larger amount.
What happens when sand or pebbles are added to water?
-Sand or pebbles do not dissolve in water; they form a heterogeneous mixture, which is non-uniform and can be seen as separate particles with the naked eye.
What are some common examples of solutions?
-Common examples of solutions include cold drinks, clouds, smoke in the air, and mixtures of alcohol and water.
Why is water called the universal solvent?
-Water is called the universal solvent because it has the potential to dissolve many substances, especially polar solutes, making it a versatile medium for various solutions.
What determines whether a substance is soluble in water?
-The solubility of a substance in water depends on its polarity. Polar substances and polar solutes are soluble in water, while non-polar substances and non-polar solutes are not.
How does the concept of solute and solvent relate to vinegar?
-In a vinegar solution, acetic acid is the solute because it is present in a smaller amount, and water is the solvent as it is present in a larger amount.
What role does the concept of solution play in everyday life?
-Solutions play a significant role in everyday life, from the beverages we drink to the air we breathe, which contains various dissolved gases and particles.
How can the understanding of solute and solvent help in the kitchen?
-Understanding solute and solvent can help in the kitchen when dissolving substances like sugar or salt in recipes, which affects the taste, texture, and appearance of the final dish.
What is the significance of a homogeneous mixture in chemistry?
-A homogeneous mixture is significant in chemistry as it represents a consistent and stable state where the components are evenly distributed, which is crucial for accurate measurements and reactions in chemical experiments.

🌊 Introduction to Solutions
This paragraph introduces the concept of a solution by using everyday examples of water with added substances like salt and sugar. It explains that a solution is a homogeneous mixture where the solute (salt or sugar) is completely dissolved in the solvent (water), resulting in a uniform composition that is not visibly separable. The paragraph also distinguishes between soluble and insoluble substances, using sand or pebbles as an example of the latter, which form a heterogeneous mixture when mixed with water.
📚 Understanding Solute and Solvent
The second paragraph delves deeper into the roles of solute and solvent in a solution. It clarifies that the solute is the substance present in a smaller amount, while the solvent is the one in a larger amount. Using salt and sugar solutions as examples, the paragraph illustrates how salt and sugar act as solutes, and water as the solvent. It also provides additional examples of solutes and solvents in various solutions like vinegar, milk, and smoke. The paragraph concludes with an explanation of why water is known as the 'universal solvent,' highlighting its ability to dissolve many polar substances, but not non-polar ones.

Highlights
A solution is defined as a homogeneous mixture of two or more substances.
Salt and sugar are examples of solutes that dissolve completely in water to form a homogeneous mixture, hence they are soluble in water.
Sand or pebbles do not dissolve in water, resulting in a heterogeneous mixture, which is not considered a solution.
Cold drinks, clouds, smoke, and alcohol mixed with water are all common examples of solutions.
In a solution, the component present in smaller amount is called the solute, while the one in larger amount is the solvent.
Water is considered a universal solvent due to its ability to dissolve many substances, especially polar solutes.
Carbon dioxide, sugar, and flavors dissolved in water make up cold drinks, which are solutions.
Clouds are solutions where water vapors are dissolved in the air.
Smoke in the air is a solution of carbon particles dissolved in the air.
Alcohol dissolved in water forms a solution where alcohol is the solute and water is the solvent.
In a salt solution, salt is the solute and water is the solvent because of their respective quantities.
In a sugar solution, sugar is the solute and milk is the solvent due to the smaller quantity of sugar.
Acetic acid in vinegar is a solute and water is the solvent, forming a solution.
The concept of solute and solvent is crucial in understanding the composition of solutions.
The ability of water to dissolve substances makes it a key component in many solutions.
The distinction between homogeneous and heterogeneous mixtures is based on the uniformity of the composition.
The solubility of a substance in water is determined by its polarity, with polar substances being soluble and non-polar substances being insoluble.
