Chemistry through Inquiry Teacher Guide

(PS-2871C)

Features over 25 inquiry based labs covering the fundamental concepts of lab skills, structure & properties of matter, chemical reactions and more.

Single Replacement Reactions

Lab Summary

Use a colorimeter to determine the mass of copper consumed and silver deposited in a single replacement reaction.

Theory

Determine the mass of copper consumed and silver deposited in a single replacement reaction. Through this investigation, students:

  • Understand single replacement reactions.
  • Learn about the activity series of metals and how it is used to determine whether or not a chemical reaction will occur.

Method

Students conduct the following procedures:

  • React solid copper with silver nitrate solution and measure the absorbance of the resulting copper(II) nitrate solution.
  • Determine the concentration of Cu2+ ions by analyzing a graph of absorbance versus concentration.
  • Calculate the amount of copper consumed and silver deposited in the reaction using stoichiometry.

Sensors / Equipment Used:

PASPORT Colorimeter Sensor
