General Chemistry
普通化学是化学专业的入门课程，系统介绍化学的基本概念和原理。内容包括原子结构、元素周期律、化学键、分子间作用力、化学平衡、酸碱反应、氧化还原反应、热力学基础、动力学初步以及溶液化学等。通过本课程的学习，学生将建立对化学学科的整体认识，掌握化学基本计算能力，为后续专业课程的学习奠定坚实基础。
General Chemistry is the introductory course for chemistry majors, systematically presenting fundamental concepts and principles. Topics include atomic structure, periodic law, chemical bonding, intermolecular forces, chemical equilibrium, acid-base reactions, redox reactions, basic thermodynamics, introductory kinetics, and solution chemistry. Students develop a comprehensive understanding of chemistry and essential calculation skills.
学生需采集当地自来水样本，使用EDTA配位滴定法测定水中钙镁离子总硬度。通过查阅资料了解常见水质软化方法，包括离子交换法、石灰苏打法、膜分离法等。设计一套适合家庭使用的低成本水质软化方案，对比不同方法的优缺点、成本和适用场景，并撰写完整的实验报告。
Students collect local tap water samples and determine total hardness by EDTA complexometric titration. Research common water softening methods including ion exchange, lime-soda process, and membrane separation. Design a low-cost household water softening solution, compare advantages, costs, and applications of different methods, and write a complete lab report.
