Question:

Explain how to prepare 100 mL of a 0.00200 M solution of NaCl by diluting a 0.500 M stock solution. The only glassware available for you to use is 1-mL, 5-mL, and 10-mL volumetric pipets and a 100-mL volumetric flask.

Dilution:

For quantitative dilution, the volumes of the stock solution and the final solution should be known or at least recorded to determine the concentration of the final solution or the stock solution. In this way, the concentration of the stock solution is decreased through the addition of solvent making the solution less reactive or less susceptible to another solution.

The equation that will be used is shown below.

{eq}\rm C1V1 = C2V2 {/eq}

where:

  • C1 - initial concentration (0.500 M)
  • V1 - initial volume (unknow...
