This unit was delivered to cover unit 8 of the IB - Acids and Bases, however it would be suitable for most post-16 programs of study.
It begins by recapping the subjects that students should be familiar with from GCSE, before building into more advanced topics. Each PowerPoint comes with a ´student version´ which has gaps for the students to complete, and contains several exercises for students to do. I have also included past paper questions and answer schemes.
Topics covered are:
- What are acids and bases?
- Bronsted Lowry acids and bases (and conjugate acids and bases)
- Amphiprotic and amphoteric substances
- Lewis acids and bases
- Reactions of acids with metals, metal oxides, metal hydroxides, metal carbonates and metal hydrogencarbonates, bases and alkalis
- Making salts
- What is pH and how to calculate the pH of both acids and bases
- Using the dissociation constant of water to calculate pH
- Acid deposition - how it occurs and how it can be treated
- Calculations involving Ka, pKa, Kb, pKb, pH and pOH
- Using the relationships Kw = Ka x Kb and pKa + pKb = pKw
- Titration curves for titrations involving any combination of strong and weak acids and bases
- Indicators - how to select a suitable indicator for a titration
- How to calculate the pH of salt solutions
- Buffers - what are they, how are they made and how do they work (including calculations)
