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.

Description

The experiments in this kit have been designed to introduce students to the concept of molarity. Students will first try to make a solution with a specific molarity demonstrating the importance of good laboratory technique. In the second set of experiments students will perform a titration on a known acid solution before using the concepts they have learned to identify the concentrations in three unknown solutions. This kit has enough materials for 15 groups. Teacher's Manual and Student Study Guide copymasters included.
