pH of Salts

Wait, what? How does a neutralization reaction have a pH other than seven? Expose one of the great grey areas of general chemistry using a video from JFR Science. The narrator explains what types of acids and bases may interact in a not-quite-neutralization reaction and how to examine an acid-base reaction to determine if this might occur.

Instructional Ideas
  • Introduce the concept after your class has mastered typical pH systems
  • After the video, show learners some acid-base pairs and ask them to guess what the neutralization reaction would produce in terms of pH
Classroom Considerations
  • Make sure pupils are proficient at calculating pH and determining the strengths of acids and bases
  • This video is hosted on YouTube
Pros
  • The opening of the video is a funny way to break the ice and own up to omitting these types of acid-base interactions when teaching the basic reaction types
  • Presents explanations in a thoughtful, detailed manner
Cons
  • None
