Course description
This class is a laboratory exercise exercise for first grade of applied chemistry department. Chemistry is a field for describing, explaining and predicting real world phenomena supported by "experiments" to observe and measure real world phenomena. Therefore, the experiment is a very large proportion for chemistry research at university.
Various preparations are necessary to do the experiment. In order to conduct experiments safely it is necessary to learn knowledge and know-how. Experience in handling experimental equipment and equipment is also necessary. You also need to learn about the method of processing measurement data and the explanation method of experimental results. The purpose of this class is to establish these foundations.
Another important purpose of this class is to deepen the understanding of the laws and principles governing chemical reactions through experiments. All the themes covered in the experiment are all important as a basis for chemistry. Let's not only mechanically execute a given menu, but also to understand the observed phenomena deeply.
This class consists of experiments and PC exercises. In the experiment, you will first work on systematic analysis of cations, which is the basis of inorganic qualitative analytical chemistry. Subsequently, you will work on quantitative measurements which form the basis of physical and inorganic chemistry, such as measurement of Avogadro's constant, light absorption analysis, measurement of molecular weight, determination of acid dissociation index. We will also conduct experiments that form the basis of organic synthesis. In the PC exercise, you will learn how to use chemical drawing software, ChemDraw, and spreadsheet software, Excel.
Purpose of class
The purpose of this class is to establish a foundation so that you can do chemical experiments safely, efficiently, and fruitfully in the advanced course for learning chemistry.
In this class you will gain the knowledge and know-how necessary to safely carry out chemical experiments. You will also master basic experimental operations of chemical experiments. In addition, you will learn how to handle and show measurement data. You can also learn how to use tools indispensable for chemical research through PC exercise, ChemDraw for chemical structure drawing software and spreadsheet software Excel. In order to be able to report and discuss on the experimental results from a chemical (scientific) point of view, you will be trained by daily guidance and interview by instructors. You will also improve common skills for communication and presentation through these communication with instructors.
Goals and objectives
  1. You can recognize the risks and environmental impacts of chemical experiments and take the necessary considerations to reduce them.
    (Corresponding to No.1 in the lesson plan)
  2. Understand the theory of solubility products and common ion effects through experiments.
    (Corresponding to No.2 to 5 in the lesson plan)
  3. Enable quantitative handling of experimental data through experiments such as measurement of Avogadro's constant, light absorption analysis, measurement of molecular weight, determination of acid dissociation index, etc.
    (Corresponding to No.6 to 11 in the lesson plan)
  4. Using PC, you can draw chemical structural formulas, tabulate measurement data, and create graphs.
    (Corresponding to No.12 and 13 in the lesson plan)
  5. Develop communication skills and presentation skills by creating experiment reports and interview by instructors.
