Description
Your lab manager has asked you to prepare 210.0 mL of 1.00 MM lead(Il) acetate solution 93911 R quantitatively (numerically accurate). Generate a plan to produce the solution. In the lab, you have
A scale that measures to 0.1 mg with a maximum load of 5 g.
. Volumetric flasks available in volumes of 10, 25, 50, 100, 250, 500, and 1000 mL.
Volumetric pipets available in volumes of 1, 2, 3, 4, 5, 10, 25, 50, and 100 mL.
Because the solution must be prepared quantitatively and your scale is only accurate to 0.1 mg, you MUST weigh out 210.0 mg of solid. Because of what is available to you, you must create an initial stock solution and perform a minimum of 1 dilution to quantitatively make the 1.00 uM solution.
Your chemical is commercially available as a solid powder and is cheap at high purity (>99.9%) – so you may use as much as you need to accomplish your goal. However, lead is extremely bad for human health and the environment. Therefore, disposing of aqueous lead waste IS expensive and your lab manager would like you to minimize the total volume of lead solution produced if possible.
20 points of credit will be allotted if your solution prep plan achieves the desired result.
The remaining 5 points will be allotted based on the total volume of lead waste produced along the way compared to your classmates.
