本书根据高等院校工科专业学生对化学实验学习的需求及特点编写而成。本实验教材与大学普通化学课程相对应。教材分为4部分：第1部分简要介绍实验室安全、基本实验操作及数据处理；第2部分介绍10个不同的实验，这些实验分别与普通化学教学中的化学热力学、化学动力学、溶液、电化学、配位化合物等理论内容相对应；第3部分是附录，包含实验中用到的一些数据；第4部分是化学实验报告。

Preface General chemistry and general chemistry experiments are important curriculum in an engineering university for students majoring in engineering and chemistry related. The general chemistry experiment course aims to further verify the fundamental principles of chemistry showing in general chemistry class, training professional skills by practice, provides a good link between theory and practice in general chemistry, and cultivate scientific approach in seeking the truth from facts. Through this course, students can finally improve their ability of practice, observe and analysis when face to problems in further study and daily lives. This book was designed to help students majoring in engineering or biology to find their special interests in chemistry experiments as non-professional chemists. This book includes 10 experiments. This book includes 10 experiments. Dr. Wangchang Geng provided the writing outlines and requirements. Experiments 1~3 were edited by Dr. Fang Chen, Experiments 1~3 were edited by Dr. Fang Chen, Experiments 4~6 were edited by Dr. Wangchang Geng, Experiments 7~10 were edited by Dr. Jing Yan Dr. Jing yan. Dr. Xin Wang was responsible for the correction of this text book. Authors would like thank these teachers from the Teaching and Research Group of General Chemistry in NPU for their generous help with the preparation of this book. Your comments or feedback about this book are most welcome. Wang chang Geng Jing Yan Fang Chen Xin Wang
