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
