Making Sodium Acetate: Hot Ice

In this chemistry activity which should only be done under adult supervision (page 10 of the PDF), learners will create an exothermic process by making Sodium Acetate. Students will boil a mixture of baking soda and vinegar to form a solution of Sodium Acetate. Once cooled, this solution will readily crystalize. Although this activity was created as a post-visit for a workshop about chemistry in cooking, it also makes an excellent stand-alone activity.
