# A-level Chemistry/OCR (Salters)/Chemical Ideas

Chemical Ideas is one of the two textbooks that were designed to be an integral part of the Salters Advanced Chemistry course. It is published by Heinemann. Chemical Ideas contains the theoretical component of the course. Its counterpart, Chemical Storylines, focuses more on the history, applications and importance of various aspects of chemistry.
A sortable table of contents for Chemical Ideas is available here.
