Description

To succeed in this topic, you need to:

  • Be familiar with the Brønsted-Lowry theory for acids and bases.
  • Be familiar with pH as a scale used to specify the acidity of an aqueous solution.
  • Be aware that buffer solutions contain a mixture of a weak acid and its conjugate base, and are used to maintain a near constant pH.

After working through this Chemistry Factsheet, you will:

  • Be able to correctly calculate the pH of a solution; and the H+ concentration in an aqueous solution of known pH.
  • To be able to correctly calculate the acid dissociation constant (Ka), the OH− concentration using the ionic product for water (Kw), and use pKa values.
  • Be able to define buffer solutions and explain how they work to maintain pH when an acid or a base is added to the solution.
