Dilution Examples in Chemistry
Start with the recap, study the fully worked examples, then use the practice problems to check your understanding of Dilution.
This page combines explanation, solved examples, and follow-up practice so you can move from recognition to confident problem-solving in Chemistry.
Concept Recap
The process of adding more solvent to a solution in order to lower its concentration.
Watering down a drink—same amount of flavor, more liquid, weaker taste.
Read the full concept explanation →How to Use These Examples
- Read the first worked example with the solution open so the structure is clear.
- Try the practice problems before revealing each solution.
- Use the related concepts and background knowledge badges if you feel stuck.
What to Focus On
Core idea: The moles of solute remain constant during dilution — only the volume and concentration change.
Common stuck point: Always add acid to water when diluting, never water to acid — the heat released can cause dangerous splashing.
Worked Examples
Example 1
easySolution
- 1 Use M_1V_1 = M_2V_2: 6.0 \times 100 = 1.0 \times V_2.
- 2 V_2 = 600\,\text{mL}.
- 3 Water to add = 600 - 100 = 500\,\text{mL}.
