What can we learn from this TGA Thermal Curve?
A We must first list all pertinent information we know about the sample before we can
analyze the data. In this case of calcium carbonate we know:
• CaCO3 is an irritant!; so be careful handling the sample, wear eye protection
• It is hygroscopic (it absorbs or attracts moisture from the air).
• Upon heating calcium carbonate it undergoes a reaction where bound CO2 is
released from the material and only calcium oxide remains after the experiment
