What This Document Is
This document is the pre-lab assignment and data sheet for the sixth laboratory experiment in General Chemistry Lab II (CHE 112L) at Eastern Kentucky University. It prepares students for an experiment focused on chemical equilibrium and factors that can shift it, as well as saturation and solubility. The document combines preparatory questions with a structure for recording experimental observations and data.
Why This Document Matters
This pre-lab assignment is crucial for students enrolled in CHE 112L. Completing it *before* the lab session ensures they understand the underlying principles and safety considerations. The data sheet provides a standardized format for recording observations during the experiment, which is essential for accurate analysis and reporting. Successful completion demonstrates preparedness and contributes to the overall lab grade. It’s designed to be used *during* the lab period to guide the experiment and record results.
Common Limitations or Challenges
This document is a preparatory and recording tool, not a comprehensive guide to chemical equilibrium. It doesn’t *teach* the concepts; it *tests* existing understanding and provides a framework for data collection. Students will still need to rely on lectures, textbooks, and their instructor for a complete grasp of the theory. This preview does not include the detailed experimental procedure itself, nor the data analysis questions.
What This Document Provides
The full document includes:
* A 20-question pre-lab assignment covering key concepts related to chemical equilibrium, saturation, and solubility. Questions address criteria for equilibrium, factors affecting it, and observable changes.
* A data sheet with sections for recording data from three parts of the experiment: Saturated Sodium Chloride, observing acid effects, and observing base effects.
* Grading rubrics for the pre-lab assignment, data recording, and overall lab performance.
* Space for instructor feedback on student performance and lab cleanliness.
* Specific questions relating to observations made during the experiment.
