**课程名称：** 酸与碱：入门 **课程概述：** 本课程旨在深入探讨水溶液中酸和碱的性质。课程首先介绍水溶液中酸和碱的定义，随后详细讲解各种多质子酸及其识别方法。通过化学方程式，我们将区分强酸/强碱与弱酸/弱碱。此外，课程还将介绍共轭酸/碱对和水的自偶电离。 我们将推导弱酸和弱碱的平衡常数，并探讨 pH/pOH 标度的数学特性。计算部分将从计算水合氢离子和氢氧根离子浓度以及 pH、pOH 的基本方法开始。接着，课程将深入讲解在水溶液中处理强酸和强碱的计算，包括如何计算在特定体积溶液中溶解多少克物质才能达到特定 pH 值。 在对强酸和强碱有扎实的理解后，我们将转向研究浓度平衡中的弱酸和弱碱。我们将学习如何构建和使用 ICE（初始、消耗、平衡）表格来计算弱酸或弱碱的 pH 值。最后，课程将通过使用多个 ICE 表格和平衡常数，指导学员计算弱多质子酸溶液的最终 pH 值。 **本课程不包含中和反应的内容。**
The course focuses on the nature acids and bases in aqueous solutions. We first cover the definitions of acids and bases in aqueous solutions. We will then discuss various polyprotic acids and how to identify them. Using chemical equations, we will define the difference between strong and weak acids/bases. We will identify conjugate acid/base pairs in chemical equations as well as autoionization. We will derive equilibrium constants for weak acids and bases and discuss the mathematical nature of the pH/pOH scales. Calculations start with simple determination of pH, pOH and concentrations of hydronium and hydroxide ions. We will them move onto calculations with strong acids and bases in aqueous solution, including calculating how many grams must be dissolved in a set amount of solution to give a specific pH. After a good understanding of strong acids and bases is established, we will work with weak acids and bases in equilibrium. We will learn how to construct and use an ICE (initial, consumed, equilibrium) table to determine the pH of a weak acid or base. Finally, we will calculate the final pH of weak polyprotic acid solutions using multiple ICE tables and equilibrium constants. We will not cover neutralization reactions in this course.
