Introduction
Determining the purity of mixture can offer a chemist a number of options. Choosing the best process among the possibilities often involves considering factors such as complexity of the process, safety and handling, cost, and disposal of waste. In this investigation, you will practice various methods of testing a mixture. A major consideration in the testing, analysis, evaluation, and recommendation will be the principles of the laboratory concept known as Green Chemistry.
What is Green Chemistry? The U.S. Environmental Protection Agency (EPA) describes the mission of Green Chemistry as the design of chemical processes and products in a way that reduces and/or eliminates the production of substances that are hazardous to humans, animals, and the environment.
Objectives
The objective of this investigation is to determine the amount of each substance in the mixture. There are many ways to accomplish this objective, three of which will be presented in the Initial Investigation.
In addition, you will evaluate the three methods of testing, with regard to accuracy, ease of operation, and the principles of Green Chemistry in order to recommend one method.
