In your studies of chemical reactions, you will have encountered ion-exchange reactions. Elsewhere, this particular type of reaction may be referred to as precipitation reaction or even double displacement reaction. Regardless, it involves a reaction between two soluble compounds to produce a precipitate (of an insoluble compound). A reaction between the reactants will depend on whether one of the products is insoluble. Solubility rules help determine if a given salt is soluble or not.


Discrepant Event

Two white crystalline salts are mixed and shaken vigorously in a canister. You’ll have to watch the video to see the rest.

And the question is: What happened?

Concepts involved:

  • ion-exchange reaction/precipitation reaction/double displacement reaction, solubility rules, soluble salts, insoluble salts.
