Practice Dilution in Chemistry

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

The process of adding more solvent to a solution in order to lower its concentration.

Watering down a drinkβ€”same amount of flavor, more liquid, weaker taste.

Example 1

easy
How much water must be added to 100\,\text{mL} of 6.0\,\text{M HCl} to make a 1.0\,\text{M} solution?

Example 2

medium
A stock solution of \text{H}_2\text{SO}_4 is 12.0\,\text{M}. What volume is needed to prepare 500\,\text{mL} of 0.60\,\text{M} solution?

Example 3

easy
You dilute 50\,\text{mL} of 4.0\,\text{M NaOH} to a final volume of 200\,\text{mL}. What is the new concentration?

Example 4

easy
How much 6.0\,\text{M} hydrochloric acid is needed to prepare 250 mL of 1.5\,\text{M} HCl?
