In this task, you are to prepare 3 × 100 mL solutions of acetic acid at 3 different concentrations. You are provided with a stock solution at 2 % and will need to perform 3 dilutions. Complete the table below to calculate how much of the stock solution and how much water is required to prepare these solutions. For this calculation the following equation may be useful: C₁ V₁ = C₂ V₂ Where C₁ is the initial concentration of the stock solution, V₁ is the amount of stock solution you need to add, C₂ is the final concentration that you desire and, V2 is the final volume that you desire.

Question
In this task, you are to prepare 3 × 100 mL solutions of acetic acid at 3 different concentrations.
You are provided with a stock solution at 2 % and will need to perform 3 dilutions. Complete the
table below to calculate how much of the stock solution and how much water is required to prepare
these solutions.
For this calculation the following equation may be useful:
C₁ V₁ = C₂ V2
Where C₁ is the initial concentration of the stock solution,
V₁ is the amount of stock solution you need to add,
C2 is the final concentration that you desire and,
V2 is the final volume that you desire.
All the values for this equation have been provided, aside from V₁ which you will need to solve the
equation to determine.
+
Solution 2 Acetic acid at 0.5 %
Solution 3-Acetic acid at 0.2%
Solution 4 - Acetic acid at 0.1%
Amount of stock solution to
add
A student uses the 1% acetic acid stock solution to make a new dilution for an experiment.
The student takes 32 mL of the stock solution and makes a dilution with a final volume of 50
mL. What is the concentration of this solution?
