SUMMARY

To prepare 100 mL of a 0.00200 M NaCl solution from a 0.500 M stock solution, first calculate the volume of the stock solution required using the dilution formula (C1V1 = C2V2). This results in a need for 0.4 mL of the 0.500 M NaCl stock solution. Use a 1-mL volumetric pipet to accurately measure 0.4 mL of the stock solution, transfer it to a 100-mL volumetric flask, and then fill the flask with distilled water up to the 100 mL mark. This method ensures precise dilution and accurate concentration of the final solution.

PREREQUISITES
  • Understanding of molarity and dilution principles
  • Familiarity with volumetric glassware, specifically volumetric pipets and flasks
  • Basic laboratory techniques for measuring and transferring liquids
  • Knowledge of NaCl properties and its applications in laboratory settings
NEXT STEPS
  • Study the dilution formula and its applications in solution preparation
  • Learn about the proper use of volumetric pipets and flasks in laboratory settings
  • Research the properties and uses of sodium chloride (NaCl) in various experiments
  • Explore common laboratory practices for preparing solutions of different concentrations
USEFUL FOR

Students in chemistry labs, laboratory technicians, and anyone involved in solution preparation and dilution techniques.

Hello, this is my first post on this forum.

I'm doing a prelab and the question asks:
Explain in details how you would prepare 100 mL of a 0.00200 M solution of NaCl by diluting 0.500M stock solution. The only glassware available for you to use are 1-mL, 5-mL, and 10-mL volumetric pipets and 100-mL volumetric flask.

I'm not sure what exactly I should explain. If someone could guide me through this, thanks in advance.

List steps - like taking a sample (what volume?) with a volumetric pipette, transferring it to a flask, filling up with water to the mark.
