The book describes the theoretical foundations of analytical chemistry, which is a branch of chemistry that studies the composition of substances and their properties using quantitative methods. It covers topics such as chromatography, spectroscopy, and electrochemistry, and provides a comprehensive overview of the principles and techniques used in analytical chemistry. The book is divided into several chapters, each of which focuses on a specific aspect of analytical chemistry. Chapter one introduces the fundamental principles of analytical chemistry, including the concept of atoms and molecules, the periodic table, and the laws of thermodynamics. Chapter two discusses the different types of chromatography, including gas chromatography, liquid chromatography, and thin-layer chromatography. Chapter three covers spectroscopy, including infrared, ultraviolet-visible, and nuclear magnetic resonance spectroscopy. Chapter four explores electrochemistry, including the principles of electrochemical cells and the application of electrochemical methods in analytical chemistry.
