You work for a company that purchases buffers in dry form, in small envelopes similar to those in which sugar is packaged. Laboratory technicians make buffers by adding one package to 500 mL distilled water. You are asked to design an experimental plan to test the effectiveness of these buffers. Write a report describing your experiment(s) and proposing actions to be taken should your experiments determine that the effectiveness is too low or too high for the intended application within your company.
