KIT MOLARITY LAB INVESTIGATION

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.
