Chapter 14.1, Problem 3SSC

Interpretation Introduction

Interpretation:

To identify different types of solution and their characteristics.

Concept introduction:

Solution can be defined as a homogenous mixture that consists of two components solute and solvent.

Solvent: Solvent can be defined as a component that dissolves other component.

Solute: Solute can be defined as a component that is dissolved in the other component, solvent.

Answer to Problem 3SSC

Solution can be classified into different types on the basis of solute and solvent:

1. Different types of solutions with water as solvent-Aqueous solution, Non-aqueous solution

2. Different types of solutions based on amount of solute added-Supersaturated solution,   saturated solution, unsaturated solution

3. Different types of solutions based on amount of solvent: Dilute solution, Concentrated solution 

4. Different types of solution based on physical state of solute and solvent

5. Different types of solution based on amount of concentration of solute

Hypertonic solutions, Hypotonic solutions, Isotonic solutions

Explanation of Solution

Types of solutions and their characteristics:

Solution can be classified into different types on the basis of solute and solvent:

1. Different types of solutions with water as solvent:

Aqueous solution −  The solution in which a solute completely dissolves in water is called an aqueous solution. Examples: sugar, salt in water.

Non-aqueous solution −  The solution in which a solute dissolves in other solvent than water is called non-aqueous solution. Examples: sulphur in carbon dioxide.

2. Different types of solutions based on amount of solute added:

Supersaturated solution:  The solution which comprises of a large amount of solute and solute is dissolved by raising the temperature.

Saturated solution: The solution in which a solvent is not capable of dissolving any more solute at a define temperature.

Unsaturated solution:   The solution in which a solvent is capable of dissolving more solute at a define temperature.

3. Different types of solutions based on amount of solvent:

Dilute solution:  A solution which contains a small amount of solute in a large amount of solvent.

Concentrated solution:  A solution which contains a large amount of solute dissolved in a small amount of solvent.

4. Different types of solution based on physical state of solute and solvent:

S. No	Types of Solution	Solute	Solvent	Examples
1	Solid-solid	solid	solid	Brass, bronze, Cranberry grass
2	Solid-liquid	solid	liquid	Solution of sugar, salt in water.
3	Solid-gas	solid	gas	Smoke
4	Liquid-solid	liquid	solid	Gelatin
5	Liquid-liquid	liquid	liquid	Alcohol in water
6	Liquid-gas	liquid	gas	Aerosol
7	Gas-solid	gas	solid	Hydrogen in palladium
8	Gas-liquid	gas	liquid	Whipped cream
9	Gas-gas	gas	gas	A mixture of gases

5. Different types of solution based on amount of concentration of solute

Hypertonic solutions: The solutions which have a higher solute concentration in beaker than inside the cell. That’s why water comes out of cell making it plasmolyze.

Hypotonic solutions: The solutions which have lower solute concentration in beaker than inside the cell. That’s why water moves into the cell.

Isotonic solutions: The solutions which have a same solute concentration in beaker and inside the cell. That’s why water will move around the cell in both directions.

Conclusion

Solution can be classified into many different types on the basis of solute and solvent
