DESCRIPTION
Here's the flow chart that I was able to pull out using RCK-002.Note: the instructions found in the lab book were rather vague; as a result, this flowchart is also vague.TRANSCRIPT

Lab for 10/29/09
Write a report
The report is worth 50 points.See Zumdahl textbook pages 684-88
and 834-5 for more information.Be sure to follow the guidelines of
your previous lab report.
Obtain a mixture melting point (to verify last week's identification)
Determine the melting point of your unknown.Determine the melting point of what you think your
unknown is for comparison and verification.
Obtain the Infrared spectrum of unknown acid
Make sure you saved your sample from last week.
Bring the dry solid to the infrared spectrometer room to obtain
spectrum.
Instructions for obtaining the spectrum (diffuse reflectance) are posted next to the spectrometers.
Read RCK-002 and SUPL-005
You should already have read SUPL-005 for the spectroscopy labs.
RCK-002 is only 2 pages of text.Pay close attention to the latter half
of SUPL-005, which deals with infrared spectroscopy.
