These notes cover the second part of the CCEA GCE AS module 1 course (Units 1-7) and were written by me last year to prepare for my AS Chemistry exam in which I got an ‘A’ grade. They are handwritten using GoodNote. This set of notes covers redox reactions, the halogens, titrations and qualitative tests.
