General Chemistry 1B Videos
This collection of videos is a supplement to the directions in the laboratory handbook. Be sure to ask your instructor for details about what they require in your data workup. A high speed internet connection is highly recommended due to the file size.
You will need the Adobe Shockwave Flash Plug-in or Viewer to watch these videos. You can download the shockwave player for free on the Adobe Website
