In recent years，in order to improve critical thinking and creative abilities for undergraduate students to design and interpret various chemical experiments，teaching objectives have been changed from traditional knowledge delivery to the integration of scientific knowledge and experimental development.Experimental training is an important route for innovative ability development，and thus，a specific guide containing an effective pathway for practical studies with a clear development direction is crucial for undergraduate teaching and studies in the 21st century.
University experimental studies in chemistry have attracted more and more attention which has led to the success of high-quality student development.As a general experimental course for non-chemistry majors，this textbook contains a wide range of fundamental chemical knowledge and principles for students during their scientific and engineering studies.Moreover，since English is the most widely used language in the world，most of the up-to-date research and reports in almost all fields are written in English.It is crucial to develop students’ability to use English in chemistry，including technical terms，accurate definitions and experimental procedures.By completing the core practical activities，students should gradually develop the ability to collect and analyze various scientific data.Moreover，students should gain experience in following and interpreting experimental instructions with minimal support，and therefore，be able to operate various analytical instruments and work safely in the laboratory.Finally，the main objective of this practical course is to help students achieve a quantitative as well as a qualitative understanding of the basic concepts of chemistry.Based on this background，this textbook offers the following advantages：
1.Novel scientific teaching content
In order to update the experimental concepts which match international research and development in chemistry，some of the conventional verification experiments have been omitted in this textbook.On the other hand，a large number of experimental designs and content modules have been newly introduced，and thus，enhancing students comprehensive capabilities and analytical skills.
2.Integration with the latest research outcomes
Based on the focus of experimental studies，a large number of novel scientific research achievements have been highlighted in this textbook.By introducing some of the "intriguing" findings in the newly published papers，students are encouraged to investigate scientific truths through various experimental designs and studies.
3.Cultivation of research and communication skills
By the end of this course，students should be able to use a variety of instruments，equipment and techniques to design and conduct both practical activities and their own investigations.They will learn to collect reliable measurements，analyze data，and draw valid conclusions in English reports using appropriate chemical terminology.
The textbook is primarily authored by Dr.Zihua Wang and Professor Shuzhong Zhan from the School of Chemistry and Chemical Engineering，South China University of Technology.The authors wish to thank Dr.Lingyu Liu from Xuchang University for her support and contributions to the graphic design of certain experimental sections.
