Gravimetric Analysis

Testing for Contaminants in Drinking Water

Topics: Molar Mass, Balancing Reactions, and Using Stoichiometry
Through a combination of particulate-level representations and virtual lab activities, students learn how gravimetric analysis can be used to determine the concentration of various species in water. Students review precipitation reactions and use the virtual lab to find out which chemicals react to form a precipitate. Using stoichiometry to connect mass to concentration, students determine if the water is safe to drink based on EPA guidelines.
