1. Identify common physical and chemical properties of acids and bases.
2. Discuss the definitions of acids and bases and relate these to their properties.
3. Explain what dissociation constants indicate about acids and bases.
4. Use experimental data to calculate a dissociation constant.
5. Identify four types of salts and determine the relative pH of its water solution.
6. Identify the relative pH of various common “household” chemicals.
7. Discuss the role of indicators and identify several common ones.
8. Describe the pH scale and calculate various concentrations using experimental data.
9. Define a buffer and explain how buffers work.
10. Perform several acid-base titrations and use the data to calculate various concentrations.
11. Identify the five most common acids, bases and indicators.
