Here is a video that is a double displacement delight! Show young scientists how to tackle the longest (and most interesting) chemical reactions to write with a video from JFR Science. The narrator shows examples of double displacement reactions, how to manipulate the ions in the equation, and how to apply the solubility rules to determine if a precipitate will form.
- Use the video to combine teaching double displacement reactions and the solubility rules
- Perform some double displacement reactions after the video to capture students' interest
- Pupils should be comfortable with ionic compounds—making them, naming them, and taking them apart
- The explanations of soluble and insoluble compounds are spot on
- The example of the use of a barium sulfate double displacement reaction to study the upper GI tract adds an element of interest to the lesson
