1. Assuming the tonic water used in an experiment contains 50 ppm quinine, what will be the final diluted concentration after following the dilution here:
-Pipet 5.00 mL of Tonic Water into a 250 mL Volumetric flask. Dilute to the mark with 0.05MH2SO4 and mix thoroughly.
-Pipet 5.00 mL of the above solution into a 25 mL Volumetric flask. Dilute to the mark with 0.05M H2SO4 and mix thoroughly.
2. Based on the answer to number one, determine a good range of quinine concentrations to analyze, and develop a plan for dilution to create 5-6 standards within that range.
A few things to keep in mind: you will be given a 1 L stock solution of 100.0 ppm quinine in 0.05 M H2SO4 as well as a separate 1 L of 0.05 M H2SO4. All standards will be made using these two components. You will use 100 mL volumetric flasks, and can use 1, 5, 10 and 20 mL volumetric pipettes.
