Course Content
A. Safely handle and dispose of hazardous chemicals
1. Research, extract relevant information and report published MSDS (Material Safety Data Sheets)
2. Categorize and segregate hazardous waste according to compatibility
3. Apply care and skill in the safe handling of hazardous compounds
B. Practice common laboratory techniques through guided inquiry labs that include the following or equivalent alternative:
1. Simple and fractional distillation of ethanol produced from fermentation of sucrose
2. Steam distillation of limonene extracted from orange peel
3. Polarimetry of limonene extract
4. Thin-layer chromatography to characterize and assess the purity of an unknown compound
5. Column chromatography to separate a mixture (ferrocene and acetylferrocene, or another similar mixture of organic solids)
6. Acid-base extraction of a mixture containing two unknowns (carboxylic acid and neutral solids)
7. Identification of organic compounds by melting point and mixed melting point analysis
8. Recrystallization from single and mixed solvents
9. Microscale distillation in the acid catalyzed rearrangement of an alcohol
10. Microscale extraction and recrystallization
C. Analyze data published in primary literature
1. Deduce whether or not data supports a hypothesis
2. Relate graphical displays to current theoretical models
3. Evaluate and discuss experimental results
4. Present and justify deductive reasoning to support experimental results
D. Analysis of experimental design
1. Hypothesis, deduction and isolation of variables
2. Data analysis and precision/error assessment
