CHEM 112: chemistry ii (science majors), laboratory

This is the second half of a two-semester course sequence designed to lay a firm foundation for more advanced chemistry and other science courses. Not only will you apply all the crafts you mastered and all the skills you acquired from CHEM 111, but you will also utilize new analytical techniques and instrumentation. In CHEM 112, the primary focus of the laboratory exercises is no longer solely the manipulation of laboratory equipment and data collection. Instead, an emphasis is placed on obtaining accurate data, data analysis, and a broad-based understanding of the implications of the experimental results. In CHEM 114, you will learn new topics beyond the scope of CHEM 105 and 106, such as UV-Vis spectrophotometry and the synthesis of nanomaterials. 

With almost two semesters of general chemistry completed, you will be adequately prepared to execute a nanomaterials research project. The results of this project will be reported formally in a scientific paper. Writing the research paper project will require you to combine general chemical knowledge, laboratory skills, analytical thinking, and creativity into a scholarly narrative. By the end of the course, you will participate in a mock peer-review process. Herein, you will develop skills to read critically scholarly articles published in scientific journals.

• Concurrent enrollment or an ABC grade in CHEM 106 is required to proceed with CHEM 112.

• An ABC grade in CHEM 111 or CHEM 113 is required to proceed with CHEM 112.

• CHEM 112 can be substituted for CHEM 114.

  • In other words, non-Chemistry majors can take CHEM 112 for CHEM 114 credits.
