Measurement and Synthesis in the Chemistry LaboratoryDescription |
- For a two-semester General Chemistry laboratory.
- This laboratory manual contains thirty-three chemistry experiments designed to introduce students to the world of chemistry and to teach them general and specific laboratory skills. Using a variety of techniques -and substances that are familiar in everyday life - they engage students in such activities as synthesizing a substance, finding the composition of an ore sample, checking the effectiveness of an antacid, etc. Each well-structured, illustrated lab features background information, a theoretical framework for the experiment, necessary mathematical derivations, a summary and checklist of general laboratory activities, step-by-step procedures, safety precautions, and pre- and post-lab exercises and report forms (on tear-out pages). Several appendices cover common laboratory operations and statistical treatment of data.

Features |
Each experiment consists of several sections: - The Introduction presents background information about the experiment, connects the subject matter to everyday experiences, discusses applications of the experimental procedure or the substances used, and - in general - attempts to raise students' interest in the experiment. Pg.___
- The Concepts of the Experiment section provides the theoretical framework for the experiment and is designed to be studied before coming to the laboratory. Pg.___
- The Activities section summarizes the work to be performed during the laboratory period. Pg.___
- The Safety section identifies potential hazards that might be encountered during work in the laboratory. Pg.___
- The Procedures section gives a detailed, step-by-step description of each operation needed for the experiment. Pg.___
Features drawings (on the left part of the page) that illustrate the text and show how equipment should be assembled, how solutions should be mixed, how thermometers should be read, how filtrations should be performed, etc. Pg.___
- A set of exercise/report tear-out pages include:
- Several appendices are provided at the back of the manual:
