Students will learn about acids and bases through a class discussion and then test a dilute acid and dilute base with neutral litmus paper to learn how the paper indicates something is acidic or basic. Once that skill is learned they can move on to test some common items that would be found around their house to determine if they are acids or bases. Optional: Extra litmus paper is included to test more items either from home or around the school building for a greater understanding of acids and bases. The activity contains enough materials for 6 groups of students.


Safety Data Sheet

Description
Employ Hess's Law of enthalpy based on the observed data for two reactions. Students can measure the temperatures of the reaction in a calorimeter and analyze the data calculating the enthalpy of each reaction. This experiment can be completed in about an hour.
