I will be teaching our one semester Inorganic course (with lab) in the Spring for the first time.  I am working on the lab syllabus and would love to know your must-do/favorite/fail proof (ha) experiments.  I've gotten a few good ideas from those posted to the forums, but am interested in hearing about some of the classics on your syllabus as well.  What experiment(s) do you do that students get the most out of?  What experiment(s) do they enjoy the most? Thanks.
