Edexcel 9-1 CC8a Acids, Alkalis + Bases CC8b Looking at acids (H) TOPIC 3 PAPER 1 Chemical change

Edexcel CC8 Acid and Alkalis for the new 9-1 GCSE
TOPIC 3 Chemical changes PAPER 1- NEW for SEPTEMBER 2017

Learning objectives: LESSON 1
To recall some common acids and bases
To explain the use of the pH scale and the use of indicators
To describe neutralisation in terms of H+ and OH- ions

LESSON 2:
To know the difference between dilute and concentrated solutions in terms of ions(H)
To explain in detail how the changes in concentration of hydrogen ions affect the pH of a solution (H)
To explain the difference between weak and strong acids, with respect to the degree of dissociation of ions (H)

All extension questions available on each slide
Answers all underneath each slide
Support also available where necessary
AfL sections and mini quizzes
Reducing the need for photocopying

Main topics include:
- dilute and concentrated
- changes in the concentration of H+ and how it affects the pH
- difference between strong and weak acids
- hazard symbols
- effects of acids and alkalis on some common liquids
- what does the pH tell us about the ions in a solution
