Introductory Chemistry, Third Edition is designed for a one-semester, introductory or preparatory chemistry course. Students taking this course need to develop problem-solving skills—but they also must see why these skills are important to them and to their world. Introductory Chemistry extends chemistry from the laboratory to the student’s world. It motivates students to learn chemistry by demonstrating how it plays out in their daily lives.

　　The third edition continues to employ Tro’s proven pedagogical features: the Solution Map provides a visual approach showing students how to think through a problem and formulate a solution strategy; the unique Three-Column Problem-Solving Procedures describe a problem-solving procedure while demonstrating how it is applied to two different examples. In addition, the Conceptual Checkpoint features now include questions that prompt students to visualize the molecular world around them.

　　Introductory Chemistry, Third Edition will automatically come packaged with MasteringChemistry?, the most advanced chemistry homework and tutorial system available. This online homework and tutoring system utilizes the Socratic Method to coach students through problem-solving techniques, offering hints and simpler questions on request. It tutors students individually with feedback specific to their errors. MasteringChemistry? helps students learn, not just practice.
