What This Document Is
This document is a lab report submitted by a student, Destiny Cambero, for CHEM 111 (General Chemistry) at Citrus College. It details an experiment focused on determining the limiting reactant in a mixture of calcium chloride dihydrate and potassium oxalate monohydrate. The report includes experimental results, observations, and a discussion of the findings. It was completed on July 5, 2018.
Why This Document Matters
This type of assignment is crucial for students in introductory chemistry courses. It demonstrates their ability to apply concepts of stoichiometry, chemical reactions, and experimental procedure to a practical laboratory setting. Instructors use these reports to assess student understanding and lab skills.
Common Limitations or Challenges
This is a single student’s work and represents one interpretation of the experiment. It does not serve as a comprehensive guide to the experiment or a substitute for course materials. It focuses solely on the specific results and analysis of one student.
What This Document Provides
The full report includes: a stated conclusion identifying the limiting reactant and its percentage composition within the unknown salt; a discussion of the experimental goal, hypothesis, and observed results; details regarding challenges encountered during the experiment (e.g., equipment issues); and considerations regarding procedural choices (e.g., filtration method, drying technique) and their potential impact on results. This preview does *not* include the raw data collected during the experiment, detailed calculations, or a full error analysis beyond the reported standard deviation.
