What This Document Is
This is a detailed pre-lab guide for CHEM 14CL, General and Organic Chemistry Laboratory II at UCLA, specifically focused on an experiment involving amino acids. It’s designed to prepare students for a hands-on laboratory experience centered around quantitative chemical analysis. This guide outlines essential preparatory work required *before* entering the lab, ensuring a safe and productive experiment. It’s dated Spring 2005, but the core principles and preparatory requirements remain valuable for understanding the experimental process.
Why This Document Matters
This guide is crucial for any student enrolled in CHEM 14CL who is about to perform the amino acid determination experiment. Successfully completing the pre-lab assignments is a mandatory component of the course and directly impacts your ability to participate effectively in the lab session. It’s best used well in advance of your scheduled lab period to allow ample time for thorough preparation and understanding of the concepts. Students who proactively engage with this material will be better equipped to handle the experiment and interpret the results.
