dc.description.abstract | Analytical chemistry laboratory manual was developed for the student in the Division of Enviromental Science and Technology, Faculty of Science and Technology, Rajamangala University of Technology Phra Nakhon, with the aim of promising the laboratory skill of the student in the preparation and standardize the solution, gravimetric analysis, volumetric analysis, and finally spectroscopy analysis. Traditionally, in the analytical laboratory, pricey analytical grad of the reagent with large amounts and quantities is required. Moreover, some of them are toxic and harmful to the environment. These can cause a problem for the university in which, the budget is limited. In this work, the idea of the small but powerful experiment was conducted. All the chemical and reagent was reduced to 50%. In the final laboratory, instead of costly and toxic reagent, some substances were replaced with the natural material such as water extraction from purple cabbage. According to the results, the developed experiments were accurate enough for practicing the student except for the precipitation titration experiment. In order to evaluate the understanding, a mini-project was assigned to the student in the group. By using the developed manual, the student can overcome the problem in the lab, and the awareness of the environment was also improved. | en_US |
