calistry calculators

Submitted by Adam Johnson / Harvey Mudd College on Wed, 01/18/2017 - 18:17
Description

I just stumbled on this site while refreshing myself on the use of Slater's rules for calculating Zeff for electrons. There are a variety of calculators on there including some for visualizing lattice planes and diffraction, equilibrium, pH and pKa, equation balancing, Born-Landé, radioactive decay, wavelengths, electronegativities, Curie Law, solution preparation crystal field stabilization energy, and more.

I checked and it calculated Zeff correctly but I can't vouch for the accuracy of any of the other calculators. 

Inorganic Chemistry for Geochemistry and Environmental Sciences Fundamentals and Applications by George W. Luther III

Submitted by Rachel Narehood Austin / Barnard College, Columbia University on Wed, 01/04/2017 - 16:10
Description

This is a great new textbook by George Luther III from the University of Delaware.  The textbook represents the results of a course he has taught for graduate students in chemical oceanography, geochemistry and related disciplines.  It is clear that the point of the book is to provide students with the core material from inorganic chemistry that they will  need to explain inorganic processes in the environment.

Molecular Hydrogen Complexes of Mo and W

Submitted by Kyle Grice / DePaul University on Fri, 11/11/2016 - 19:28
Description

Literature discussion about the first examples of molecular hydrogen complexes isolated by Gregory J. Kubas in the early 80s. The questions are divided into groups with two levels of difficulty.

The more basic group of questions includes topics on:

1)      Coordination Chemistry: electron count, geometry, oxidation state, orbital interactions, types of ligands, binding modes, cis/trans and fac/mer isomers.

2)      Symmetry elements and point groups.

3)      Basic concepts on spectroscopy: NMR, Raman, IR, UV/Vis, XANES, EXAFS, neutron and X-ray diffraction

Building Molecular Orbitals for a Square Pyramidal Oxorhenium(V) Complex

Submitted by M. Watzky / University of Northern Colorado on Thu, 06/30/2016 - 17:21
Description

This activity guides students into building a Molecular Orbital diagram, which focuses on metal-centered orbitals of mostly d character, for a square pyramidal complex that includes different types of ligands. Students are then asked to "fill" the resulting orbitals with metal d electrons, and examine the stability of the complex.

Electrochemical and Carbonyl Frequencies to Explain Ligand Non-Innocence in Organometallic Pincer Complexes

Submitted by Bryan Sears / Emmanuel College on Thu, 06/30/2016 - 10:52
Description

In this literature discussion, students read an Inorganic Chemistry paper (doi: 10.1021/ic503062w) about diarylamido-based PNZ pincer ligands and their Ni, Pd, and Rh complexes. Specifically, this paper uses IR and E1/2 potentials to demonstrate that the redox events occur not on the metal center but on the pincer ligands.

Ligand Design for Selectivity and Complex Stability

Submitted by Daniel Kissel / Lewis University on Wed, 06/29/2016 - 00:49
Description

This is an overview of some important principles of ligand design. Topics covered include HSAB theory, the chelate effect, the chelate ring size effect, the macrocyclic effect, the cryptate effect, and steric focus in ligand design.

Online Homework for a Foundations of Inorganic Chemistry Course

Submitted by Sabrina Sobel / Hofstra University on Mon, 06/27/2016 - 18:08
Description

The Committee on Professional Training (CPT) has restructured accreditation of Chemistry-related degrees, removing the old model of one year each of General, Analytical, Organic, and Physical Chemistry plus other relevant advanced classes as designed by the individual department. The new model (2008) requires one semester each in the five Foundation areas: Analytical, Inorganic, Organic, Biochemistry and Physical Chemistry, leaving General Chemistry as an option, with the development of advanced classes up to the individual departments.

"Flipped Laboratory": A Discussion-based Electrochemistry Experiment for General Chemistry

Submitted by Samuel Esarey / University of Michigan on Mon, 06/27/2016 - 16:43
Description

This learning object is aimed at getting students to think critically about the data they collect in lab as they collect the data similar to how chemists typically conduct research.  They will be given a pre-lab video and a procedure prior to lab, conduct the experiment, and then upload their data to an Excel spreadsheet.  Students will then stay in their group to discuss the questions given to them on the worksheet in class with the instructor, and are allowed to continue working on them as a group up until the due date.
