Project title: Determining the Mechanism of Pattern Formation in Periodic Precipitation (Liesegang) Reactions
Mentor: Joel Karty
Fall 2013 was a big leap forward for our project. With the help of Austil Sowell, we were able to create a successful Liesegang reaction of cadmium sulfide. This past fall semester, we worked to fine-tune this reaction as well as study various aspects of the reaction in real time.
We were successfully able to control one of the most important aspects of the reaction, the spacing of the Liesegang bands. After thorough experimentation, we found that band spacing could be adjusted simply by changing the concentration of cadmium dissolving into the gel. Moreover, our group has directly observed the process of Liesegang band formation using a time-lapse movie. To the best of our knowledge, this may be the only footage of Liesegang rings available! Only is this an exciting creation, but it raised an important question: “Why are bands forming before the salts meet each other?”
There has been a photo going around the internet of a beautiful rock formation at Bouddi National Park, Australia. The formations are Liesegang rings! Here is a link to a nice photo.
