Edit 0 1 …
Learning Goals: (1 hour)
  • Distinguish between aqueous solutions that are acidic, neutral or alkaline using the pH scale.
  • Identify which of two or more aqueous solutions is more acidic or alkaline using pH values.
  • State that each change of one pH unit represents a 10-fold change in the hydrogen ion concentration [H+(aq)].
  • Deduce changes in [H+(aq)] when the pH of a solution changes by more than one pH unit.
