What This Document Is
This is a pre-laboratory assignment for CHEM 103, Introduction to Chemistry, at Indiana University of Pennsylvania. It prepares students for an experiment focused on acid-base reactions, titration, and pH/pOH calculations. It’s designed to be completed *before* entering the lab, ensuring students understand the underlying principles and necessary calculations.
Why This Document Matters
This assignment is crucial for students enrolled in CHEM 103 who are about to perform a titration experiment. Successful completion demonstrates preparedness and allows for a more efficient and productive lab session. It reinforces key concepts related to molar mass, indicators, molarity, and pH calculations – foundational knowledge for chemistry coursework.
Common Limitations or Challenges
This pre-lab assignment focuses on preparation and calculation setup. It does *not* provide guidance on performing the actual titration procedure in the lab, nor does it offer detailed error analysis or troubleshooting tips. It assumes a basic understanding of chemical formulas and stoichiometric ratios.
What This Document Provides
The assignment includes the following:
* Problems requiring calculation of molar mass (potassium hydrogen phthalate).
* Conceptual questions about the role of indicators in titration.
* Quantitative problems involving molarity calculations based on titration data.
* pH/pOH conversion practice.
* A table for recording data during the experiment (initial/final buret readings, volumes, concentrations).
* Procedural notes regarding syringe use and safety precautions (NaOH handling).
This preview does *not* include solutions to the problems, detailed experimental procedures, or the results of the experiment.
