Lab: Understanding the Mole Concept. In this lab, students will observe the reaction that takes place when iron filings are added to a copper sulfate solution. Students will observe the color change and watch as copper precipitates and collects in the bottom of a beaker. This lab reinforces the basic mole concept by having students calculate the number of moles of iron used, and the number of moles of copper produced.
Suitable for chemistry and physical science students in grades 9 - 12.
Purpose: To understand the meaning of the term "mole" and to enable students to gain a better understanding as to the size of a mole.
