Chapter 13, Problem 1E

What is a solution? What are the solute and solvent?

Interpretation Introduction

To determine:

The definition of solution, solute and solvent.

Answer to Problem 1E

Solution:

Solution is the homogeneous mixture of two or more components. Solute is the component which is to be dissolved in solvent for making solution.

Explanation of Solution

A solution is a homogeneous mixture of two or more chemically non-reacting substances. The mixture is perfectly uniform in its composition and properties throughout the bulk solution. A solution generally has two components- solute and solvent. Solute is defined as a substance which is present in small amount by mass and dissolved in a substance which is present in larger amount by mass said to be solvent. Like sugar solution, here sugar which is present in small amount (solute) which is dissolved in larger amount of substance, water (solvent). Such a solution which has two components is also called as binary solution. Solute and solvent can be solid, liquid or gas.

Examples,

1. Solid Solution: like Alloys. Solute is metal, or nonmetal and solvent is also metal.
2. Liquid solution: like sugar solution, ethanol in water
3. Gas Solution: like Air. It is a mixture of gases (oxygen, nitrogen, carbon dioxide etc.)

Conclusion

Solution is the homogeneous mixture of two or more components. Solute is the component which is to be dissolved in solvent for making solution.
