The main difference between solute and solvent is that a solute is a substance that gets dissolved in a solution. While the solvent is the substance responsible for dissolving the solute. The other significant difference between them is that solutes are typically present in lower concentrations within the solution. In contrast, solvents are found in higher concentrations.
One of the basic distinctions in physical sciences and chemical engineering is between solute and solvent. These terms are often encountered when discussing solutions, and knowing their differences is vital for comprehending various chemical processes.
In this article, we will explore the 10 key differences between solute and solvent in a tabular form. Whether you’re studying chemistry or need to apply these concepts in practical scenarios, this detailed comparison will help you navigate the distinctions between solute and solvent effectively.
Solute vs Solvent
|1.||Definition||The substance is being dissolved in a solution.||The substance that dissolves the solute in a solution.|
|2.||State||Can exist in solid, liquid, or gas form.||Typically, in liquid form, but can also be a gas or solid in some cases.|
|3.||Quantity||Present in smaller quantities compared to the solvent.||Present in larger quantities compared to the solute.|
|4.||Role||Undergoes dissolution; it dissolves in the solvent.||Dissolves the solute to form a solution.|
|5.||Physical Change||May not undergo significant physical changes during dissolution.||Often remains unchanged during the dissolution process.|
|6.||Chemical Change||Does not undergo a chemical change when dissolving.||Typically, retains its chemical properties during dissolution.|
|7.||Concentration||Lower concentration in the solution.||Higher concentration in the solution.|
|8||Measured in||Typically measured in grams or moles.||Usually measured in liters or milliliters.|
|9.||Effects on Solution||Impacts the properties of the solution, such as taste, color, or conductivity.||Less impact on the properties of the solution.|
|10.||Examples||Sugar in water, salt in water, or air (gases in air), etc.||Water, alcohol, or any suitable liquid, etc.|
Detailed Explanation of 10 Differences Between Solute and Solvent:
- Definition: The solute is the substance that gets dissolved in a solution, while the solvent is the substance responsible for dissolving the solute.
- State: Solute can exist in solid, liquid, or gas form, whereas the solvent is typically in liquid form but can also be a gas or solid in specific situations.
- Quantity: The solute is present in smaller quantities compared to the solvent, which is found in larger amounts in the solution.
- Role: Solute undergoes dissolution, meaning it dissolves in the solvent, while the solvent dissolves the solute, creating a homogeneous mixture.
- Physical Changes: Solutes may or may not undergo significant physical changes during dissolution, depending on their properties. Solvents often remain unchanged during the dissolution process.
- Chemical Changes: Solutes typically do not undergo a chemical change when dissolving, retaining their chemical properties. Solvents generally retain their chemical identity as well.
- Concentration: Solutes are typically present in lower concentrations within the solution, while solvents are found in higher concentrations.
- Measurement: Solutes are usually measured in grams or moles, whereas solvents are commonly measured in liters or milliliters.
- Effect on Solution: Solutes have a more significant impact on the properties of the solution, such as taste, color, or conductivity, while solvents have a lesser influence.
- Example: Common examples of solutes include sugar in water, salt in water, or gases in the air. Solvents include water, alcohol, or any suitable liquid for dissolving.
Frequently Asked Questions
1. Can you give an example of a solute-solvent relationship?
Ans: When you dissolve sugar (solute) in water (solvent), you create a sugar solution.
2. How can you determine the solute and solvent in a solution?
Ans: The substance that is present in a smaller quantity and is being dissolved is the solute, while the substance present in a larger quantity that does the dissolving is the solvent.
3. Why do some substances dissolve in certain solvents but not in others?
Ans: The ability of a substance to dissolve in a particular solvent depends on the chemical compatibility between the solute and solvent. Such as polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes.
4. What is the maximum amount of solute that can be dissolved in a solvent at a given temperature and pressure?
Ans: The maximum amount of solute that can be dissolved in a solvent at a specific temperature and pressure is known as the solubility of the solute in that solvent.
5. How does temperature affect solubility?
Ans: In many cases, solubility increases with an increase in temperature. However, this is not a universal rule and depends on the specific solute-solvent system.
6. Can you have a solution with more than one solute?
Ans: Yes, solutions can contain multiple solutes. These are called “mixed solutions,” where two or more substances are dissolved in a common solvent.
7. What happens when you reach the maximum solubility of a solute in a solvent?
Ans: When the maximum solubility is reached, any additional solute added to the solution will not dissolve and will form a separate phase or precipitate.
8. How is the concentration of a solution expressed?
Ans: The concentration of a solution is commonly expressed in terms of molarity (M), molality (m), mass percent, volume percent, or parts per million (ppm), depending on the context.
9. What is a supersaturated solution?
Ans: A supersaturated solution is one in which the concentration of the solute exceeds its normal solubility limit at a particular temperature. These solutions are usually unstable and can precipitate or crystallize if disturbed.
10. Is air a solution, and if so, what are its solute and solvent?
Ans: Yes, air is a gaseous solution. Nitrogen (approximately 78%) and oxygen (approximately 21%) are the major components (solute) dissolved in the gaseous mixture of other gases like argon, carbon dioxide, and water vapor (solvent).
