Welcome to The Virtual Laboratory


This page is an index file of Virtual Laboratory Activities and tutorials developed by UALR and the Chem Collective at Carnegie Mellon University. You will be assigned an unknown number by your instructor which you will use for the duration of the semester. Collaborative work is encouraged as every student is assigned the same problem but a different unknown. You can run the virtual laboratory from any computer with WEB access. When you first load the virtual lab it checks your PC to ensure it has all the required plugins. If it does not, you will be directed to the appropriate downloads. You can also access the virtual lab from the UALR SCLB 263 computer lab. Contact Dr. Belford or your instructor if you wish to have a CD copy of the virtual lab with all the appropriate downloads and we will provide you with one.
To access the virtual Laboratory log onto:

Virtual Laboratory Tutorials and Aids


Link Description
Introduction A quick introduction to the virtual lab and how we will be using it in CHEM 1403
User Guide PDF file User Guide. These are available in SCLB 263
Movie Tutorial Movie on how to use the Virtual Lab. Headphones are available in SCLB 263.
Tip: The movie opens in a new window and if any of the movie is cut off you should expand to the monitor's full screen size.
List Server Have Questions?You have two options. At the bottom of each lab is an "ask your instructor" option. When you use this an email is sent to Dr. Belford. He will reply with a message to the class listserver. All sections should join the CHEM140331L Listserver.
Tips: Exp. 2B SOLUBILITY CURVES You should read this before running your first virtual lab experiment
Tips: Exp. 4 Beer's Law Plot You should read this before running your experiment. These tips should save you time.
Tips: Exp. 8B Gram Equivalent Weight (Molar Mass) and Ka for an unknown acid. You should read this before running your experiment. These tips should save you time.

Experiment 2B FIRST LAB: SOLUBILITY CURVES You need to compare the solubility curve of your unknown to the five identified in the assignment. You need to hand in your solubility curve, data sheet and state the identity of your unknown
Experiment 4 Second Virtual Lab You need create a Beer's law plot for the compound provided and then determine the concentration of your unknown by comparing it to the data you obtain from the Beer's law plot. Hand in this sheet and your Beer's law plot
Experiment 4 Second Virtual Lab Directions This link takes you to a web page created from a powerpoint presentatin providing instructions on how to use the virtual spec. 20. If you have power point, you may download the presentation directly here
PreLab Experiment 8A Third Virtual Lab You need to determine Ka for your virtual unknown acid.
Experiment 8B Fourth Virtual Lab You need to determine the molar mass and Ka for your virtual unknown solid acid.
