For each part of the aspirin experiment, you will need to turn in a pre-lab for it. The following guidelines are for part 1 of the experiment.

Pre-lab Report Guidelines for Aspirin Experiment (Week 1 ONLY)
(i) Title of the experiment
(ii) Reference of procedures
(iii) Introduction
(iv) Procedures for week 1 ONLY in flow chart format
(v) MSDS information
The following chemicals will require you to use the MSDS database on the Web (see Lecture Syllabus):
Salicylic Acid, Sulfuric acid (concentrated), Acetic anhydride
You should record the following MSDS information in your notebook for the chemicals listed above.
(Printouts directly from the Web pages will NOT be accepted!!)
(a) Product Name
(b) Chemical Formula
(c) Formula Weight
(d) Melting Point; Boiling Point and Density
(e) Health Hazard Data (summarize in your own words)
(f) Spill and Disposal procedures (summarize in your own words)
(vi) Pre-lab study questions (Must show all work for FULL credit)
Complete ALL study problems under week 1.
(vii) Data/observations
Set up tables but leave blank. You MUST record all the observations into your lab notebook during your lab sessions. You will NOT receive any credit for your lab technique if you only record the weight of the chemicals for this experiment.

Postlab Report Guideline for Aspirin Experiment (Week 1)
A) Data/Synthesis (See p.94 in your lab manual)
Orderly record of data Data tables should have proper titles / labels
(B) Data Analysis (MUST SHOW ALL WORK FOR FULL CREDIT)
&Mac183; Theoretical moles of Aspirin
(MUST identify which one is the limiting reagent)
&Mac183; % Crude Yield
&Mac183; % Corrected Yield
(C) Conclusions
&Mac183; Compare % crude yield and % corrected yield with 100%. What can you conclude?
&Mac183; If your % crude yield or % corrected yield is greater than 100%, explain why.
&Mac183; If your % crude yield or % corrected yield is less than 50%, explain why.
