Instructional Ideas
- Use the video to demonstrate the formation of NaCl, especially if the experiment cannot be performed in the classroom or lab
Classroom Considerations
- Video uses chemistry terms associated with chemical reactions, such as ionization energy, Coulombic interactions, electron affinity, exothermic, etc.
- Be sure learners have enough chemistry knowledge to understand what is occurring in the video
- This video is hosted on YouTube
Pros
- The reaction produces bright orange flames, which amazes and engages learners
- Short length of the video makes it a good instruction to a more thorough demonstration or experiment in class
Cons
- Lab performer eats a hard-boiled egg, violating a basic lab safety rule
- During the demonstration, the performer pulls out a sample of previously prepared salt rather than using the results of the experiment
