The scientific discipline which deals with the elements and compounds that are composed of atoms, molecules and ions is known as chemistry. Their composition, structure, behavior, properties and the changes they undergo during a reaction with other substances are studied under chemistry. It acts as a foundation in understanding the basic and applied scientific disciplines, such as ecology, botany, geology, pharmacology, etc. Some of the important aspects studied under this discipline are chemical bonding, chemical compounds, chemical reactions, acidity and basicity, chemical equilibrium, etc. Analytical chemistry, organic chemistry, inorganic chemistry, biochemistry, physical chemistry, nuclear chemistry, etc. are some of the sub-disciplines of this umbrella field. This textbook is a compilation of chapters that discuss the most vital concepts in the field of chemistry. Some of the diverse topics covered in this book address the varied branches that fall under this subject. This textbook will provide comprehensive knowledge to the readers.
