Week 3

Read pages 104 - 107 in lab manual.

Review lectures slides on volume measurement (posted in D2L Week 3 Content).

Read textbook pages 443 - 466. (Important!)

No new references for this week.

Review the technique demonstration videos from Week 2 references, especially for any devices in which your measurements resulted in accuracy and/or precision below instrument specifications.

None for this week.

Refer to the "Additional Practice" activities posted in week 2 and continue practice as needed.

• Be able to use top-loading balances, analytical balances, graduated cylinders, serological pipettes, and micropipettes for weight and volume measurements with appropriate accuracy and precision.

Complete the Gravimetric Analysis activity.

• Finish taking all volume and weight measurements.

• Use the Calculation Template (D2L, Week 3 Content) to calculate the accuracy and precision of your measurements.

  • Know how to calculate percent error (accuracy) and average absolute deviation (precision) for measurements.

  • Use spreadsheets with formulas (like the template provided) when crunching larger data sets.

The entire lab period on Day 3 will be dedicated to Exam I.

• The exam includes a written component that covers the concepts and activities from the first three weeks of the class, and a practical (hands-on) component that covers the measurements, equipment use, and documentation that we learned so far.

No technique demonstration this week.

Use the Class Data link (D2L, Week 3 Content) to share a subset of your data from the gravimetric analysis activity.

Entries #4 is to be completed this week.

No additional practice activities for this week.

We will begin a new section of the class on the topic of pH, buffers, and solutions.

There are no assignments due before the next class.
