Topics and Learning Outcomes

  • Strong Acids and Bases
    •  list common acids and bases
    •  define acids and bases according to the Arrhenius and Bronsted-Lowry models
    •  apply equilibria to acids and bases
    •  use the definitions of pH and Kw to quantify the acidity and basicity of aqueous solutions
  • Weak Acids and Bases
    •  explain the difference between a strong and weak acid and the difference between a strong and weak base in terms of the percentage dissociation in solution
    •  explain the increase in pKa values for dissocation of the protons in a polyprotic acid
  • Calculations Involving pKa
    •  use pKw, pKa and pKb to calculate the pH of a solution containing a weak acid or base
    •  use the increase in pKa values for dissocation of the protons in a polyprotic acid to perform calculations
    •  be able to explain what buffers are and how they work
    •  be able to calculate the pH of a buffer system and be able to design a buffer with a required pH
    •  use titration curves to characterize acids and bases, using the pH at the equivalence and half-equivalence points
    •  design and perform titration experiments to obtain pKa values with appropriate choice of indicator
