Students in lab courses, such as CHEM 120 General Chemistry 2, may be asked to design their own experiments. These types of detailed methods that list chemicals and equipment can be found in books and chemical education journals. If you need help, don't be shy to email me (April) questions or schedule an appointment.

There are a few dedicated resources for finding experimental protocols. The chemical literature can also be searched with CAS SciFinder Discovery Platform, which includes CAS Analytical Methods. In addition, theses and dissertations are a great resource for detailed methods that are often overlooked.
