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
Performing liquid-liquid extractions allows students to apply their knowledge of the properties of molecules. Students will learn how the properties of solubility can be utilized to separate two solids in a mixture. This kit provides for a qualitative test that will help students visualize that two different solids were collected, despite their similar appearance. Students will also explore the concept of the law of conservation of mass as well as how acid-base reactions can be utilized to manipulate molecules. This kit contains enough material for 15 groups. Teacher's Manual and Student Study Guide copymasters are included.
