Chemistry For Your Life Chemistry at Home: Chocolate and Gum
Dec 5, 2024
Dive into the unusual world of chocolate and gum with a mouthwatering experiment! Jam shares his reluctance to mix chewing gum with creamy chocolate. As he explores flavors, listeners learn why gum doesn’t dissolve in water, thanks to its unique nonpolar structure. The hosts discuss the chemistry behind 'like dissolves like' and how chocolate’s fat interacts with gum. Plus, they offer fun ways to try this at home, making it a perfect experiment for curious kids and parents alike!

Episode notes
Jam's Gum-and-Chocolate Experiment
- Jam chewed gum and gradually added milk chocolate squares while chewing the gum the whole time.
- After eating about one and a half to two squares, the chocolate dissolved and the gum seemed to disappear, which Jam found very freaky.
Like Dissolves Like Explains Gum Behavior
- Gum is mostly long non-polar carbon chains that don't dissolve in water.
- Chocolate contains fats with similar carbon-hydrogen structures, so chocolate can interact with and dissolve gum.
Polarity Determines Solubility
- Water is polar with partial charges and doesn't interact well with non-polar gum molecules.
- Gum's electrons are evenly spread, so water can't dissolve gum but fats can due to molecular similarity.
