Concept Objectives

Sect 1: What Are Acids and Bases?

    1. Describe the distinctive properties of strong and weak acids, and relate their properties to the Arrhenius definition of an acid.

    2. Describe the distinctive properties of strong and weak bases, and relate their properties to the Arrhenius definition of a base.

    3. Compare the Bronsted-Lowry definitions of acids and bases with the Arrhenius definitions of acids and bases.

    4. Identify conjugate acid-base pairs.

    5. Write chemical equations that show how an amphoteric species can behave as either an acid or a base.

Sect 2: Acidity, Basicity, and pH

    1. Explain the relationship between pH and H3O+ concentration.

    2. Describe two methods of measuring pH.

Sect 3: Neutralization and Titrations

    1. Predict the product of an acid-base reaction.

    2. Describe the conditions at the equivalence point in a titration.

    3. Explain how you would select an indicator for an acid-base titration.

    4. Describe the procedure for carrying out a titration to determine the concentration of an acid or base solution.

Sect 4: Equilibria of Weak Acids and Bases

    1. Write an equilibrium equation that shows how a weak acid is in equilibrium with its conjugate base.

  1. Describe the components of a buffer solution, and explain how a buffer solution resists changes in pH.
