Chemistry 2e

Chemistry 2e is a full introductory chemistry textbook from OpenStax, freely licensed under Creative Commons. It builds from atoms, molecules and stoichiometry through thermochemistry, bonding, states of matter, solutions, kinetics, equilibrium, acids and bases, electrochemistry and nuclear chemistry. Clear figures, real-world applications and end-of-chapter exercises make abstract ideas concrete. For students and teachers who need a legal, high-quality reference they can freely copy and share, this book removes the cost barrier while maintaining university-level rigour.
