College Instructor edition with 36 experiments covering introductory and general chemistry topics.

Empirical Formula of Compound

Lab Summary

Use a crucible and Bunsen burner to react a chemical with air in order to determine the stoichiometric composition of an ionic compound.

Theory

Students determine the stoichiometric composition of an ionic compound.

Method

Students gain experience conducting the following procedures using a balance and a Bunsen burner to:

  • Perform a reaction under controlled conditions—heating a metal to form the metal oxide.
  • Eliminate the byproduct of a reaction and convert it to a desired product.
  • Determine the change in mass to find the stoichiometric composition of the metal oxide.

Materials Used:

Crucible with lid 
Ring stand 
Bunsen burner 
Balance - 1 per class
Crucible tongs 
Wash bottle with deionized water 
Clay triangle 
Paper clip 
Magnesium powder - 0.5 g

The Associated Bundle:
