CHEM1002 - Resources for Week 8
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
