CK-12 Chemistry Flexbooks

CK-12 provides a wide variety of grade-level course materials for K-12, and the chemistry textbooks integrate diagrams, descriptions, and outside videos.  I highly recommend these free resources.  Chemistry for High School provides a comprehensive textbook across levels, but the Chemistry Flexbooks include workbooks, lab manuals, and texts for specific courses.

OpenStax Chemistry 2e and Atoms First 2e

I can't recomment the OpenStax textbooks enough.  They're free, peer-reviewed, and detailed.  Although these college textbooks might not be the best book for every high school course, these are excellent resources for instructors who need a refresher on core concepts.  For this website, I link to the Atoms First Edition of Chemistry 2e simply because I prefer that order of chapters, but both textbooks include the same material.
