nanoCHAts: Informal conversations about teaching

A collection of all of the IONiC VIPEr NanoCHAts. These are short discussion on a teaching topic by 4-5 faculty members from different institutions. Each of these events is recorded and posted to the IONiC VIPEr YouTube Channel.

Effect of Intramolecular Hydrogen Bonding on Cupric Superoxide Complexes (Karlin)

This study guide/question set will help a student navigate through the related research paper and test the student's understanding on the effects of hydrogen bonding in synthetic Cu-O2 adducts in the realm of bioinorganic model chemistry.

Inorganic Chemistry Spectroscopy Tutorial: Theoretical Principles and Applications, Version 2.0

Submitted by Jason Cooke / Department of Chemistry, University of Alberta, Canada on Thu, 04/01/2021 - 07:34

In the 2000s, we developed an online tutorial that demonstrates the fundamental principles and applications of the various types of spectroscopy that students will encounter in the inorganic chemistry laboratory, namely infrared spectroscopy (IR), nuclear magnetic resonance spectroscopy (NMR) and UV-visible spectroscopy (UV-vis).  With the demise of the original Flash browser plug-in at the end of 2020, a revised version 2.0 has been created to update the source content to HTML5.  The tutorial has been designed as a stand-alone interactive resource that can either

reaction of PPh3 with elements--the COVID edition

This is a research-like laboratory experience based on the one posted by Brad Wile (linked below). My students are mostly juniors and have had 2 semesters of organic. This spring they are taking the inorganic laboratory virtually, so I wanted to give them a more exploratory lab experience. Their job will be to watch the YouTube videos to see the synthesis and isolated products, and then propose characterization methods they want to employ to identify both the identity and purity of the compounds.

Resolution of Werner complexes -- the COVID edition

This is a classic experiment that has been revised and updated numerous times over the years. The experiment can be found in Girolami, Rauchfuss and Angelici, 3rd edition, but that edition removed some purification steps that were present in the earlier edition which has plagued generations of my students with poor resolution of the enantiomers. Marion Cass published a J. Chem. Educ. article in 2015 that included a pH determination and added back in the recrystallization step. This allowed my students to achieve higher yields and greater resolution in Spring 2020.

metal acac complexes the COVID 19 version

Submitted by Adam Johnson / Harvey Mudd College on Mon, 01/18/2021 - 16:56

For our virtual offering of inorganic chemistry laboratory at Harvey Mudd College in Spring 2021, I made some videos and collected some high quality data (IR, 1H NMR, MS, UV-Vis, mp, and X-ray diffraction) that I will make available for my students. The videos show the synthesis of Co and Mn acacs, the difference between as-prepared and recrystallized compounds, making solutions for UV-Vis and Evans method NMR, and making Evans method capillary tubes. The procedures for the synthesis of these compounds is found in Woolins (either the first or second editions). 

SLiThEr #7: Assessment Using Literature Discussions

Submitted by Kyle Grice / DePaul University on Tue, 12/29/2020 - 17:55

This is the seventh SLiThEr () in the series. In this presentation/discussion, Dr. Shirley Lin explains how she used a literature discussion with students to assess their learning and knowledge. This was for a upper-division senior seminar course. In particular, she discusses questions at various levels of Bloom's Taxonomy. She also explains how to use concepts from Chemical Education Research to really dig down and assess student knowledge. 

SLiThEr #1: Creating online inorganic chemistry labs

Submitted by Kyle Grice / DePaul University on Tue, 12/29/2020 - 14:29

This is the link to the first SLiThEr (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable), presented by Kyle Grice and Hosted by Chip Nataro. The SLiThEr was recorded and posted on YouTube (see the web resources link). 

This particular roundtable focused on the teaching of a Junior/Senior-level inorganic chemistry laboratory completely online. Kyle presented on what he did in Spring 2020 when he had to pivot quickly to a fully remote modality with only a week or so of planning. 

Synthesis of Fluorescent Aluminum Complexes

Submitted by Taylor Haynes / California Polytechnic, San Luis Obispo on Fri, 08/28/2020 - 15:34

In this experiment, Students synthesize a Schiff Base and the corresponding aluminum complex to measure fluorescence. The lab provides exposure to air-free synthetic techniques, including the use of Schlenk Line techniques and safe handling of sure-seal bottles. Following data collection, students will be able to explain fluorescence spectroscopy and compare it to absorbance spectroscopy.
