| Course description |
|
In “Experiments in Applied Chemistry I”, we conduct experiments and practical training related to physical chemistry, inorganic chemistry, and analytical chemistry. This course is one of the series of the experimental courses (I-III) in the Department of Applied Chemistry. It consists of two parts, “Physical Chemistry Experiment” and “Inorganic Chemistry and Analytical Chemistry”. The class is divided into two classes, C1 and C2. One class conducts physical chemistry experiments followed by inorganic chemistry and analytical chemistry experiments. The other class conducts physical chemistry experiments after inorganic chemistry and analytical chemistry experiments. In “Physical Chemistry Experiments”, students learn physical chemistry experiments through thermodynamic physical quantity measurements and understand the correspondence between experiments and theories. Learn how to handle data and make appropriate charts to organize experimental results. In “Inorganic Chemistry and Analytical Chemistry Experiments”, familiarize yourself with experimental operations and handling instruments through analytical experiments centered on titration. Through these experiments, learn about safe and careful basic experimental techniques to obtain accurate measurement results. Moreover, become familiar with the correct handling of numbers as well as errors and significant figures. We also do the exercises using molecular models for spectrophotometric analysis and isomers of inorganic complexes. |
| Expected Learning |
|
In “Physical Chemistry Experiments”, students can understand that the concepts, such as enthalpy, entropy, and chemical potential, and learn thermodynamic physical quantity measurement methods. In “Inorganic Chemistry and Analytical Chemistry Experiments”, especially through chemical analyses and material syntheses, students can acquire the basic experimental techniques by ensuring the knowledge learned in the lectures on inorganic and analytical chemistry. Diploma policy perspective of this course: Please refer to the curriculum map in the course guide. |
| Course schedule |
|
The following themes will be implemented in Experiments in Applied Chemistry I. There are some themes which are conducted in groups, so please check the schedule and meeting places in the overall guidance (the date: specified later, belongings: 2021 version of student experiment textbook, and pens). Physical chemistry experiment 1. Experiment Guidance: Explanation of physical chemistry experiments, confirmation of precautions in conducting experiments, safety training. 2. Measurement of reaction heat: Learn the concepts of enthalpy and reaction heat through the reaction between hydrochloric acid and magnesium. Also, learn how to measure the heat of reaction using the volume change caused by the melting of ice. 3. Cryoscopic determination of molecular weight: Determination of molecular weight by measuring the lowering of the freezing point of a sucrose/water solution. Understanding the thermodynamic theory of the freezing and the method of least squares. Also, learn about the least squares method. 4. Partial molar volume: Confirm by the experiment that 20 ml of liquid A and 80 ml of liquid B are not necessarily 100 ml, and consider the reason using the concept of chemical potential. 5. Solubility of solids: Understand the thermodynamic concept of dissolution and observe temperature-dependent solubility changes. The solubility is grasped from the concentration measurement by ultraviolet light absorption spectroscopy (UV). This experiment is offered ONLINE. 6. Rubber elasticity / rheology: Understand that rubber elasticity is entropy elasticity. Students learn the concept of rheology in the association with various everyday phenomena. 7. Electrical conductivity of electrolyte solution: Learn the difference in concentration dependence of electrical conductivity of strong and weak electrolyte solutions. Inorganic and analytical chemistry experiments 1. Experiment Guidance: We will explain the contents of inorganic / analytical chemistry experiments, precautions in conducting experiments, and conduct safety lectures. 2. Statistical processing practice: Learn about experimental data processing methods by measuring particle size distribution. 3. Practice of molecular model: Understand the three-dimensional structure of metal complex with molecular models. 4. Neutralization titration: A typical example of volumetric analysis is neutralization titration using acid-base reaction. Master the preparation of secondary standard solutions and titration with acid-base indicators. Moreover, neutralization titration is performed using a glass electrode pH meter to prepare a pH titration curve. Learn about the equivalence point of the neutralization reaction from the titration curve, the shape of the titration curve, the strength of the acid, and the operating principle of glass electrodes. 5. Complex titration: Evaluate EDTA solution with zinc standard solution, learn about complexation reaction and metal indicator, and the theory and experimental operation about complex titration method. In addition, the determination of calcium and magnesium contained in limestone is carried out using this method. 6. Spectrophotometric analysis: Conduct an adsorption experiment of methylene blue with zeolite to deepen understanding of the adsorption evaluation method by spectroscopy. 7. Powder X-ray diffraction: Identification of the sample and information on the crystal structure can be obtained by irradiating the crystalline material with X-rays and measuring the intensity of the diffracted X-ray. Identify unknown samples by powder diffractometry and deepen understanding of crystal structure evaluation methods. |
| Prerequisites |
|
Preparatory training is essential from the viewpoint of ensuring safety in conducting practical training. Each person should carefully read the experimental texts, thoroughly understand the contents, create a flowchart of the experimental procedure, examine the physical and chemical properties of the reagents in advance, and write them in the experimental notebook (15 hours). After each experiment, an experimental report should be written. Describe the purpose, experimental procedures, results, discussions, conclusions and references appropriately according to the prescribed format, and submit them within the prescribed date (30 hours). Add 90 hours of class time and the above-mentioned learning outside the class, and prepare and review. The contents of the study are in accordance with the standard number of hours of the University. |
| Required Text(s) and Materials |
| Use the Department of Applied Chemistry experiment text (2021 edition). |

| Assessment/Grading |
| Comprehensive evaluation of report points (including test points) (50%) and normal points (including class participation and positive presenting during experiments) (50%). Guidance, lectures, and experiments should be all attended in principle. Acquiring credits may be difficult due to lateness, absence without notice, delayed or unsubmitted reports, and negligence during the experiments. |
| Message from instructor(s) |
| Safety in experiments takes priority over anything else. Prepare carefully for the experiments, and dress appropriately. |
