The main difference between Dilute Solution and Concentrated Solution: A dilute solution contains a small amount of solute dissolved in a large amount of solvent, while a concentrated solution contains a large amount of solute
Dilute Solution vs Concentrated Solution — Comparison Table
| Basis | Dilute Solution | Concentrated Solution |
|---|---|---|
| Solute Amount | Small amount of solute | Large amount of solute |
| Solvent Amount | Large amount of solvent | Small amount of solvent |
| Concentration | Low concentration value | High concentration value |
| Color Intensity | Pale or light color | Intense or dark color |
| Reactivity | Slower reactions | Faster reactions |
| pH Change with Dilution | Minimal pH change | Significant pH change when diluted |
Key Points
- Dilution is the process of adding solvent to make a solution less concentrated
- The concentration of a solution can be expressed in molarity, molality, or percentage
- Concentrated solutions are more reactive and require more careful handling due to their potency
- Dilution follows the formula M1V1 = M2V2 to calculate final concentration
Frequently Asked Questions
What makes a solution dilute or concentrated?
The proportion of solute to solvent. A dilute solution has a small quantity of solute in a given amount of solvent; a concentrated solution has a large quantity of solute in the same amount of solvent.
Are dilute and concentrated exact terms?
No, they are comparative. There is no fixed boundary between them — a solution is dilute or concentrated relative to another. For an exact statement chemists give the concentration as a number, such as moles per litre.
How can a concentrated solution be made dilute?
By adding more solvent. The quantity of solute stays the same but it is spread through a larger volume, so the concentration falls. Removing solvent by evaporation does the reverse and concentrates the solution.
