摘要:

针对复杂酸碱体系的滴定问题和氯化铅溶度积常数测定两个典型基础化学实验进行了虚拟实验设计与建设。借助于软件平台创建的虚拟实验交互系统涵盖了大量的基本理论、实验仪器与设备等信息,提供了各种反应条件下的组合实验、实验数据的计算结果与检验等,满足了学生不同层次的学习要求。

关键词: 虚拟实验, 酸碱滴定, 氯化铅, 溶度积常数

Abstract:

Design and construction of virtual experiments were carried out based on two typical basic chemical experiments, complicated acid-base titration and solubility constant measuring of PbCl2. A large amount of information about basic theories, experimental instruments and equipment were encompassed by the virtual experiment system which was created by means of a software platform. In addition, series of experiments under different conditions, calculation and inspection of experimental data were provided to meet different learning demands from students.

Key words: Virtual experiment, Acid-base titration, Lead chloride, Solubility product
