CGPwned: Your Edexcel IGCSE Chemistry Notes!

A*/A Guaranteed if you revise this and understand!:) Any questions, feel free to ask!

This is based on the edexcel textbooks - which i strongly urge you guys to get!

These notes were originally intended just for me but I felt like sharing it so there you go!

This revision guide contains:

  • Material from the 2009 Edexcel syllabus + triple science statements (i.e. single chemistry)
  • Such as the haber process, contact process, covalent bonding, electrolysis of aqueous solutions, moles - you name it!
  • Nice diagrams - some drawn, some off google images
  • And lots more!

Now go get your A*/As! hahaaaha

Oh by the way, still stuck on moles or balancing equations? Well I'll upload some of my written explanations on these - there MIGHT be errors though! Hahahahaa

Update #1: Added a last section on acids and alkalis as well as some missing bits and pieces here and there
