Lab downloads (consult syllabus for assigned dates)

The labs linked below are in .pdf format and are readable using Adobe Reader.
Download and read these well in advance of the scheduled lab activity.

To save paper, I recommend printing only the pages you will be handing in for credit.
You are welcome to use an electronic format in lab to read the instructions for the procedure.

Spectrovis spectrometers and Vernier Bluetooth pH electrodes will be used. These interface with your cell phone or computer.

Apps to control these instruments are available from from Vernier.
Spectral Analysis app (for Android or iPhone) is used to run the Spectrovis spectrometers.
Graphical Analysis is used to interface with the bluetooth pH electrodes.

This file gives instructions on using the Bluetooth spectrometer with your phone.

Expectations from CHEM 1450

New students to my class should rightly know what I expect are general laboratory skills they should have earned from CHEM 1450. This link summarizes these skills. Grading points will assume you understand and have these skills.

Safety Agreement

This must be completed to work in lab.
Be certain to adhere to the rules it describes, including shoes, clothing, and eye protection.

Electrochemistry

Answers to questions may be handwritten and should be organized to ease evaluation.

Clear formatting of sections should be used.
