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 K_w 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 pK_a values for dissocation of the protons in a polyprotic acid

Calculations Involving pK_a
- use pK_w, pK_a and pK_b to calculate the pH of a solution containing a weak acid or base
- use the increase in pK_a 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 pK_a values with appropriate choice of indicator
