Acids and Bases

Unit 1. Definition of Acids and Bases

1. 1. 1. Define conjugate acid and conjugate base and cite examples of conjugate pairs.

      2. Give in your own words definitions of acids/bases: Brønsted and Lewis.

      3. Define amphoteric.

      4. Rank species of each of the following acids based upon relative strength: hydrohalic, oxoacids, and carboxylic.

      5. Identify an acid or base as being strong or weak.

      6. Identify a species as a Lewis acid or Lewis base.

Unit 2. pH and pH scale

1. 1. 1. Use the equilibrium expression for water and its value to perform calculations and determine whether a
         solution is acidic, basic or neutral.

      2. Use the pH scale to classify a solution as being acidic, basic or neutral.

      3. Use pH, pOH, concentration of hydroxide ion, or concentration of protons to conduct calculations asking
         for one of these terms.

Unit 3 and 4. Weak Acids and Bases

1. 1. 1. Use the value of the acid-dissociation constant (Ka) in equilibrium calculations.

      2. Understand the relationship between Ka, Kb and Kw.

      3. Calculate the percent ionization of a weak acid or base.

      4. Use the pH of a weak acid or base solution to calculate the Ka or Kb, respectively.

      5. Use Kw to determine the relative strength of conjugate pairs.

      6. Identify polyprotic acids and explain why the initial ionization is easier than subsequent ones.

Unit 5. Salts

1. 1. 1. Classify a salt as being basic, acidic or neutral based upon the acid and base used to form the salt.

      2. Calculate the pH of a salt solution.

      3. Classify an oxide as being acidic, basic or amphoteric.
