Unit 7.2 Solutions
Understanding the chemistry of aqueous solutions is important in understanding water quality environmental issues. In this section a class explores the solubility of substances in water.
Video program cues: 5:05-16:20

About water

"I do the water cycle in September. I tie it into solutions and how water is a universal solvent, and has things dissolve in it. There’s a lot of chemistry in just water."

Lisa Morine
Watkins Mill High School, Maryland

Solubility class activity

Al DeGennaro classifies different compounds by their solubilities. The concepts of precipitates and insolubility are thus related.
