1) What is an Arrhenius acid/base? What is a Bronsted-Lowry acid/base? What is a Lewis acid/ base? 2) What are the differences between strong and weak Arrhenius acids and bases? Give a few examples of each. 3) How does Ka value relate to the strength of an acid? 4) Define autoionization as it applies to acid-base chemistry. In what two ways does autoionization affect aqueous acid-base chemistry? 5) Briefly explain the significance of pH, its scale, and how its value relates to the acidity and basicity of a solution? 6) What two assumptions can be made when solving problems involving weak-acid equilibria? 7) What is a polyprotic acid? Give a few examples. 8) What is Kb, and how is it related to Ka and Kw ? 9) Briefly describe how dissolving certain salts may yield neutral, acidic, or basic solutions
