The result of putting the wrong kind of acid on your chips!
Acids and bases are some of the most familiar compounds in everyday life, and most people have at least a rudimentary understanding of them. In this unit we will be looking in detail at both acids and bases, looking at two different models for describing them (Bronsted-Lowry and Lewis), their chemical properties, and the pH scale which is used to measure their ‘strength’. At HL we will bring a level of quantitative rigour to our understanding and will learn how to calculate quantities such as pH, Ka and pKb and their basic counterparts, and we will investigate buffer systems.
This unit will take around 4-5 weeks and will be assessed by a test that will also cover the redox unit.
Presentation:
You are strongly encouraged to use this in lessons, and make notes on it. Used in conjunction with the experiments it more or less contains everything you need to know.
Experiments and Worksheets:
- Strong and Weak Acids and Bases
- Calculating pH and pOH
- Determining pKa for a weak acid
- Making Buffers
- Acid-Base Titrations
- Making Natural Indicators
- Strong-Weak Calculations
On the Web:
- Very clearly written explanations on most of the course
- Clearly explained videos on each part of the topic
