Description
This course covers the fundamentals of an Analytical Chemistry course that one might take as a Chemistry major or minor. Ideally, students should have taken a year of General Chemistry as a prerequisite, as much of the material covered relies on a knowledge of equilibrium chemistry. Students in this course have access to ample supplemental material, all of which will be found in the Resource Folders. In addition to the 23 hours of lectures, downloadable audio mp3 files of each lecture are included. For many lectures, a Practice Assignment where you can test your understanding of the material can be found in the Resource Folder. Also included is an answer key for each Practice Assignment. Any graphs, figures or tables presented in the lectures are also available as downloadable files. The content of this course is as extensive as all of my other Chemistry courses are that are also available on Udemy.This course assumes that you have completed General Chemistry I and ideally General Chemistry II college courses. While you will not need to be familiar with all topics covered in those courses, you should have a good understanding of equilibrium Chemistry. As with my other intermediate courses that I have posted on Udemy, I have review sections for important chemical concepts that are needed for this course.*Since this course covers the fundamentals of Analytical Chemistry, most instrumental techniques such as Atomic Absorption, UV-Visible Spectrophotometry, Infrared Spectroscopy, Chromatography and Nuclear Magnetic Resonance are not covered. Section 15 is an introduction to Instrumental Analysis where I introduce colorimetric analysis and Beer's Law, which is the basis for most Instrumental methods. Anyone who is interested in learning about various aspects of Analytical Chemistry may find this course beneficial, especially if you had no prior exposure to Analytical Chemistry in your studies.
