Describe the water's role in aqueous acid-base chemistry 2. Identify the conjugate base of an acid, the conjugate acid of a base, and the relationship between conjugate acid and base strengths. 3. Recognize how amines act as bases and how carboxylic acids ionize in aqueous solution 4. Use the autoionization of water and show how this equilibrium takes place aqueous solutions of acids and bases 5. Classify an aqueous solution as acidic, neutral, or basic based on its con titration of H3O+ or OH6. Calculate pH (or pOH) given [H3O+], or [OH-] given pH (or pOH) 7. Estimate acid and base strengths from Ka and Kb values. 8. Describe the acidic behavior of hydrated metal ions 9. Write the ionization steps of polyprotic acids 10. Calculate pH from Ka or Kb values and solution concentration 11. Describe the relationships between acid strength and molecular structure 12. Explain the nature of zwitterions 13. Describe the hydrolysis of salts in aqueous solution 14. Apply acid-base principles to the chemistry of antacids, kitchen chemistry, and household cleaners 15. Recognize Lewis acids and bases and how they react
