Acid-Base Dissociation Equilibrium in Multiphase System:Effect of Gas
摘要
Abstract
Acid-base equilibrium is a crucial topic in chemical education.However,current teaching practices only focus on describing acid-base dissociation and pH buffering in homogeneous solutions,without considering the influence of gas-phase components on acid-base dissociation and pH buffering in multiphase systems.To address this issue,this paper takes a typical aerosol multiphase system as an example and examines the impact of component volatility and hygroscopicity on the acid-base equilibrium in multiphase systems through the analysis of multiphase buffering theory and the effective dissociation constant p Ka*.By doing so,it aims to stimulate students'thinking and provide a new paradigm for teaching acid-base equilibrium in multiphase systems.关键词
