Beer's Law Lab - Guided Inquiry Activity |
|
Popis
|
The learning goals of this guided-inquiry activity are as follows: Students will be able to, (a) Describe the relationship between solution concentration and the intensity of light that is absorbed/transmitted; (b) Explain how wavelength, solution color, and absorbance are related by comparing different solutions; and (c) Use a sketch of an absorption spectrum to describe the concept of maximum
absorbance wavelength.
This activity was originally developed for a recitation/tutorial which precedes a wet lab on FeNCS2+ spectroscopy. Instructors can edit the last question to refer a solution the students will use in a lab or demo, or use it as is to serve as an extension question even if no benchtop lab will be performed. There is a remote lesson that could be used by individual students if an in class setting is not available. |
