REQUIRED MATERIALS

You will need three things for this laboratory:

• • • A laboratory notebook subscription from LabArchives.com

    • Safety glasses/goggles (also available from the Chemistry department office)

    • A USB flash drive to move data files from the lab computers to your lab notebook

GRADING

The laboratory is worth 20% of your overall course grade, with 60% of that total coming from individual experiments, and 40% coming from a final project. Individual experiment grades generally consist of the following:

• • • • • • Moodle pre-lab quizzes (10 pts)

          • Lab reports (20 pts)

            • • • Lab report scores are usually based on both calculations (10 pts) and overall accuracy (10 pts)

          • Notebook completeness (5 pts)

          • Lab cleanliness - the lab should be kept lab free of clutter, trash, leftover chemicals, spilled chemicals, and extra equipment. Points may be deducted from individuals or the entire class if all work areas are not cleaned up after use.

SCHEDULE

The first seven experiments will introduce you to instruments and techniques commonly used in analytical chemistry:

Week 1:

• • • • • • • Statistical Comparison of Titration Techniques

Weeks 2-7 (rotation):

• • • • • • • Atomic Absorption Determination of Iron in Cereal

            • HPLC Determination of Phthalates in Waters

            • Ion Chromatography Determination of Anions in Water

            • Multicomponent UV Analysis to Determine Caffeine and Benzoic Acid in Soft Drinks

            • Simultaneous Determination of Manganese and Nickel in Steel by Inductively Coupled Plasma Atomic Emission Spectrometry

            • GC-MS Determination of Bisphenol A in Water

During weeks 2-7 I'll assign you an experiment for that week. Then I will open your Moodle pre-lab quiz and it must be completed before you perform that experiment.

Following these introductory experiments, we'll turn our attention to experiments related to our class project: the chemical analysis of a real-world sample. Each of these experiments will use one of the instruments previously introduced to measure a particular component of the sample. At the end of the semester, the results of these analyses analysis will be compiled in a report written in the form of a scientific journal article.
