Demonstration should include
- explaining the difference between stock solution and working solution
- following the steps for weighing and measuring, as well as the importance of accuracy, precision, and record-keeping in the process
- incorporating the concepts of normality and molarity, as well as dilution techniques and the purpose of reagents.
Process/Skill Questions:
- What could be the result of improper measurements when diluting calibration material?
- What dilution techniques are commonly used when mixing reagents and solutions?
- What is the procedure for weighing and measuring when making stock reagents and solutions?
- Why is it important to include a mix date on solutions and reagents?
- What type of record-keeping is used when making reagents and solutions? Why is record-keeping important when making reagents and solutions?
