Environment: Urban
 
Big Idea:

One component of water quality is pH, which tells us how acidic or basic a solution is; acids and bases have different properties; living organisms typically prefer neutral solutions.

Water Quality: Removing Contaminants Day 1

High School Chemistry » Unit: Environmental Applications of Chemistry
High School Chemistry » Unit: Environmental Applications of Chemistry
Emilie Hill
Los Angeles, CA
Environment: Urban
 
Big Idea:

Water pollutants from industry are usually in the form of large organic molecules and metallic ions; we can remove these contaminants using small particles to "soak" up the contaminants.

Water Quality: Removing Contaminants Day 2

High School Chemistry » Unit: Environmental Applications of Chemistry
High School Chemistry » Unit: Environmental Applications of Chemistry
Emilie Hill
Los Angeles, CA
Environment: Urban
 
Big Idea:

Adding particles that react with contaminants will remove those contaminants from solution; we can filter "used" cleaning particles from solution to result in clean water samples.
