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."

- This site is devoted to a "Cyber Field Trip Teaching
Guide - Water World: The Blue Planet" based on a
Scientific
American Frontiers program from 1999. Procedures for
water quality studies are included.

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