Coordination chemistry via Inorganic Chemistry ASAP

Submitted by Hilary Eppley / DePauw University on Mon, 09/14/2009 - 11:23
Description
This in-class activity is a fun way to show students how to apply basic concepts of coordination chemistry to complicated systems that appear in a recent issue of Inorganic Chemistry. After quickly reviewing types of ligands (monodentate, chelating, bridging), how we assign charge to ligands and metals in complexes, and the idea of coordination number, I took my class through a number of "real world" examples from the latest ASAP edition of Inorganic Chemistry.

Sol-Gel Silica: Nanoarchitectures of Being and Nothingness

Submitted by Maggie Geselbracht / Reed College on Thu, 08/06/2009 - 16:59
Description

In this lab experiment, students use sol-gel chemistry to prepare silica gel monoliths from tetraethylorthosilicate (TEOS).  Carrying out the hydrolysis and condensation under acid-catalyzed vs.

First Day Review of Atomic Orbitals

Submitted by Maggie Geselbracht / Reed College on Mon, 07/27/2009 - 22:30
Description

This is an interactive small-group discussion activity I did on the first day of sophomore-level inorganic chemistry to get students to interact with each other and brainstorm to collectively review what they knew about atomic orbitals.  I also wanted to "set the stage" for non-lecture type activities in this class.  I adapted this in-class activity from one posted by Joanne Stewart (Hope College) with additional questions from a fundamental quiz posted by Barbara Reisner

Theo Gray's Mad Science: Experiments You Can Do at Home--But Probably Shouldn't

Submitted by Hilary Eppley / DePauw University on Wed, 07/08/2009 - 16:18
Description

Theo Gray has compiled some of his Popular Science columns into a beautiful book of sometimes dangerous experiments, many of them with particular relevance to inorganic chemistry! With chapter names like "Experimental Cuisine", "Doomsday DIY", and "Twisted Shop Class", you know you in for a wild ride. Some particularly intriguing experiments include electroplating a copper design on your iPod, making glass and elemental silicon out of sand, making a burning Mg/dry ice sculpture, anodizing Ti for cool color effects, and creating a "hill billy hot tub" using 600 lbs of quicklime.

Molecular Orbital Diagrams

Flash based tools to help with the construction of MO diagrams:

  • "energy levels" shows how the form of the bonding and antibonding orbitals, the bond order and atomic charges vary in a diatomic molecule with the electronegativity of the two atoms involved
  • "Molecular orbital diagram maker" shows how a complex MO diagram can be made by a drag and drop approach using symmetry adapted components

 

The Elements: Theo Gray's periodic table website

Submitted by Hilary Eppley / DePauw University on Thu, 07/02/2009 - 16:47
Description

While this site is also a commercial site (selling Theo's periodic tables and book, etc.) it is a wonderful resource of pictures of elements and their compounds, and "real life" uses of elements (such as a gamma ray imaging of the skeleton for Tc, a hard drive for B, and sushi for Hg!). It is also a source of movies of reactions of the elements, including some pretty impressive ones for the alkali metals and the thermite reaction. It also provides easy access to his chemistry column for Popular Science magazine.

Periodic Table Formulations

Submitted by Barbara Reisner / James Madison University on Thu, 07/02/2009 - 10:56
Description

This website provides access to many formulations of the periodic table over time. I think that looking at the various representations of the table would provide an excellent way to discuss periodic trends.

This list was compiled by Mark R. Leach and is part of his free resource, The Chemogenesis web book.

Coordination Chemistry Nomenclature

Submitted by Maggie Geselbracht / Reed College on Sat, 04/25/2009 - 22:19
Description

I usually do not take time in my inorganic course to teach students about how to name coordination complexes. And yet, I would like them to know nomenclature to the extent that they can correctly name various complexes in their lab reports or understand the naming conventions used in the literature. Often, there is a section in their textbook that I can refer them to. However, this year, I am using Housecroft and Sharpe, and I could not find the appropriate sections in the text. So, I found some online resources to refer my students to.

Glassware and Apparatus Videos

Submitted by Jason Cooke / Department of Chemistry, University of Alberta, Canada on Wed, 04/15/2009 - 18:07
Description

A series of videos has been produced to show students the best way to assemble glass jointware.  A variety of different examples are provided, with variations that demonstrate some of the more complicated assemblies that are often used in inorganic synthesis (e.g., how to protect the system with a drying tube or to purge an apparatus with an inert gas).  The intent of the videos is to provide visual learners with a better idea of what they must do in the laboratory, and thereby speed up the process of assembling glass jointware.

Videos include:
