How weak is a weak base? Science scholars develop more than a basic understanding of the base dissociation constant with a video from the JFR Science playlist. The narrator shows how to perform dissociation constant calculations and how to compare these values for acids, bases, and water.

Concepts

Instructional Ideas

• Use the resource to supplement an acid-base chemistry unit
• Challenge learners to find examples of strong and weak bases in household products
  

Classroom Considerations

• Spend some time before the video reviewing the structure of bases
  

• This video is hosted on YouTube

Pros

• Description of how to differentiate strong and weak bases through nomenclature is spot-on
• The use of quinine and tonic water as an example is engaging and interesting
  

Cons

• None
