Product Description

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.

======================================================================================================

Please Note: This lab is also sold in a bundle containing 14 "must-do" physical science and chemistry labs. View the bundled product by clicking this link.

What will the students be doing?

  • Students will add iron filings to a hot copper sulfate solution. Students can observe a color change as iron replaces copper to form iron (II) sulfate.
  • Students will observe the precipitation of copper out of the solution as it settles to the bottom of a beaker.
  • Students will calculate the number of moles of iron used and the number of moles of copper produced.
  • Students will visually see that a chemical reaction is taking place.
  • Students will collect quantitative data to prove that mass is conserved during a chemical reaction.
  • Students will complete calculations and answer 7 analysis questions.

MATERIALS AND EQUIPMENT:

Copper (II) sulfate pentahydrate, Ring stand with ring, Wire Gauze, Iron filings, Bunsen Burner, Distilled water, 100 mL Beaker, Weighing Paper, 250 mL Beaker , 100 mL Graduated cylinder, Balance, Glass Stirring rod, Drying Oven
