Title: Quantitative and Qualitative Analysis 
Purpose: The purpose of this experiment is to learn how to measure the amount of a substance 
that is present in a chemical compound. A metal carbonate will be analyzed to determine how 
much CO2 and moles of CO2 are lost. Another experiment will also look into how much water a 
hydrate loses and determine what type of hydrate it is. Paper chromatography will be used to 
determine the identity of chemical substances. Lastly, SEM/EDX will be used to d...
