课程名称：高级化学 概述：本课程涵盖高级高中化学课程中选定的主题，与美国化学学会确定的标准主题相对应。 先决条件：学生需具备基础化学知识，包括命名法、反应、化学计量、摩尔浓度和热化学。 课程大纲： 1. **反应动力学** 描述：研究化学反应随时间变化的过程，解答变化期间的相关问题。 2. **化学平衡** 描述：介绍化学平衡的概念及其在许多化学反应中的应用。通过讨论质量作用定律和物质的浓度及压力与平衡常数之间的关系，深入探索平衡的定量方面。将学习如何解决问题以找到平衡常数的值或反应物在平衡状态下的浓度，并引入初始-变化-平衡（ICE）表作为解决问题的工具，附有多个示例。 3. **酸碱平衡** 描述：将平衡的概念应用于酸碱溶液。首先探讨弱酸和弱碱的概念及其在水中电离的平衡常数，如何将平衡常数的值与酸或碱的强度联系起来。讨论水的自电离及温度如何影响此过程，涵盖多种问题类型，包括强弱酸碱的pH、pOH、[OH-]和[H+]计算。此外，对水合盐溶液进行酸碱分类，并讨论多质子酸的多步电离，最后讨论路易斯酸碱的概念并通过实例展示。 4. **水相平衡** 描述：继续并扩展平衡主题，考察缓冲溶液、酸碱滴定以及难溶盐的平衡。 5. **热力学** 描述：热力学的核心主题是预测在特定条件下反应是否会自发发生。定义并利用熵和自由能来进行这一预测。
Part: 1
Title:Kinetics
Description:The study of chemical kinetics is the study of change over time. It answers questions like:
Part: 2
Title:Chemical Equilibrium
Description:This unit introduces the concept of chemical equilibrium and how it applies to many chemical reactions. The quantitative aspects of equilibrium are explored thoroughly through discussions of the law of mass action as well as the relationship between equilibrium constants with respect to concentrations and pressures of substances. Much of the discussion explores how to solve problems to find either the value of the equilibrium constant or the concentrations of substances at equilibrium. ICE (initial-change-equilibrium) tables are introduced as a problem-solving tool and multiple examples of their use are included.
Part: 3
Title:Acid-Base Equilibria
Description:The concept of equilibrium is applied to acid and base solutions. To begin, the idea of weak acids and bases is explored along with the equilibrium constants associated with their ionization in water and how the value of the equilibrium constant is associated with the strength of the acid or base. The autoionization of water is discussed and how temperature affects this process. A variety of problem types are covered including calculations of pH, pOH, [OH-], and [H+] for both strong and weak acids and bases. Aqueous salt solutions are classified as acids and bases and the multi-step ionization of polyprotic acids is discussed. Finally, the concept of Lewis acids and bases is discussed and demonstrated through examples.
Part: 4
Title:Aqueous Equilibria
Description:This unit continues and expands on the theme of equlibria. You will examine buffers, acid/base titrations and the equilibria of insoluble salts.
Part: 5
Title:Thermodynamics
Description:The overarching theme of thermodynamics is the prediction of whether a reaction will occur spontaneously under a certain set of conditions. Entropy and Free Energy are defined and utilized for this purpose.
A chemistry course to cover selected topics covered in advanced high school chemistry courses, correlating to the standard topics as established by the American Chemical Society. Prerequisites: Students should have a background in basic chemistry including nomenclature, reactions, stoichiometry, molarity and thermochemistry.
