AQA GCSE chemistry - Unit 4 - Lesson7 Strong and Weak Acids and understanding pH

This is a lesson to teach strong and weak acids with an introduction to the meaning of pH. It has a ppt and worksheet in word and pdf format with answers to the worksheet as well.

1. The meaning of strong acid in terms of complete ionisation of acid molecules in water
2. The meaning of weak acid in terms of partial ionisation of acid molecules in water
3. Comparison of the terms concentrated and dilute with strong and weak and an explanation of how a weak acid can still be concentrated and a strong acid could still be dilute.
4. Grid to test understanding of key vocabulary in the ppt file.
5. Meaning of pH in terms of the change in 10x each time you go down a pH unit - does not include logarithms it is described in an accessible way that allows students to calculate changes in concentration as pH unit changes.

I write Professor Bunsen resources to teach and test in my own classroom. I hope that I manage to make the new GCSE in chemistry engaging and exciting. Most importantly it could save you and your school time!
