A picture is worth a thousand words

One of my research students is working on a project in which we are doing halide abstraction from a metal center. In theory, she is generating KCl which will precipitate out of the reaction mixture. Sure enough, she gets a precipitate. The solution was filtered and the remaining solid was dried in vacuo. The solid had some slight color to it as well as a heterogenous appearance. When she adds some water most (but certainly not all) of the solid dissolved.

An update on X-ray

I've previously posted on a wonderful lab that can be found here on VIPEr. The lab describes the synthesis of zinc oxide nanoparticles which are then characterized by powder XRD. One of the wonderful aspects of VIPEr is the interaction of the community. And for me, to be able to try out this lab, and then get insight and feedback from the author was incredibly useful.

Sophomore symmetry

Submitted by Chip Nataro, Lafayette College

This spring I am doing something new in my sophomore inorganic class. Before I go into detail, a little background is needed. This class has a fairly academically diverse population. The prerequisite for the course is General Chemistry II. I have senior biochemistry majors that have had two semesters of P-chem as well as first year students that have only had General Chemistry II. I also have a fairly high population of chemical engineering majors. As I said, academically diverse.
