EXPERIMENTS AND EXERCISES FOR CHEMISTRY COURSES
The 6th edition of the lab text Experiments in General Chemistry was published in 2015. While changes were submitted for newer printings or a 7th edition, the lab book market does apparently not justify the printing of more improvements to the manual. During the preparation of each edition, an effort was made to include discovery inquiries into each experiment. Many of the experiments are variations of experiments found in both commercially available lab books as well as in-house materials. However, there are a few experiments which are signifiicantly different in content than other published materials. As a result, it was felt that posting of those experiments could be useful to chemistry laboratory supervisors and permission was sought and granted by Cengage to make them available free on the Internet. Previously, an extension of one of the experiments (a titration experiment) was published in the Journal of Chemical Education.

Links to Experiments 1, 2 and 3 are provided below. Two of the material science experiment links are also available below.
Experiment 1. http://murov.info/chemexpts1.pdf COMPLEXES - A series of reactions involving possible complex formation is studied and observations are compared to predictions calculated from complex formation constants. A set of seven unlabeled bottles are identified by comparison of experimental observations with a prediction matrix. A qualitative analysis scheme is developed and tested on an unknown.
Experiment 2. http://murov.info/chemexpts2.pdf REDOX REACTIONS - Reduction potentials will be used to predict the outcome of several redox reactions and the predictions will be compared to experimental observations.
Exercise 3. http://murov.info/chemexpts3.pdf GRAPHING QUANTITATIVE RELATIONSHIPS - Several exercises have been designed to develop graphing skills. Also available in an htm file: http://murov.info/chemexpts3.htm
Exercise 4. SEARCHING FOR CHEMICALS:
A MATERIAL SCIENCE LESSON
FOR CHEMISTRY STUDENTS. PARTS 1, 2 and 3
Exercise 4 involves some materials that were included in the lab book but much more content has been added. Enough so that it was beneficial to divide it into three parts. The intent of the exercise is to provide experience with often overlooked approaches to the learning of chemistry. First, polymers, metals and metal alloys are part of many of the problems and challenges. Second, students are asked to think about the properties of substances desirable for specific applications and then to search for and identify substances with the needed properties. This might fall into the realm of material science but provides students with a different and stimulating approach to the learning of chemistry.
