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.
