OCR A level Chemistry Chapter 20 Model answer revision notes

Trying to move from a D/C to a B/A/A* in Chemistry?
Using my 6 years of teaching experience, looking through** past papers**, mark schemes and examiner’s reports, I have created a concise revision note pack.

This is in the format of having a standard question followed by bullet points of the answers/keywords you need to include to score full marks. At the end of each topic, I have listed common mistakes made by students and explained why those mistakes are incorrect. This has been based on feedback given by examiners every year.

I have started using these with my A-level classes and have seen their grades and confidence in Chemistry improve immensely.

Lessons included in this pack:

20.1 - Bronsted-Lowry acids and bases
20.2 - The pH scale and strong acids
20.3 - The acid dissociation constant Ka
20.4 - The pH of weak acids
20.5 - pH and strong bases

Please leave a review and send me an email to get another one of my notes for free!
