Water is essential to life (cont.)


We continued our notes on why water is really pretty amazing. We focused on the following key ideas:





1. Insulation of Water by Floating Ice
2. Water is the Solvent of Life
3. Hydrophilic and Hydrophobic Substances
4. Solute Concentration in Aqueous Solutions
5. Dissociation of water molecules leading to changes in pH
6. The pH scale and how to determine a pH by looking at the concentration of hydroxide ions.


Homework: B Block has a quiz on Chapter 3 on Saturday, D Block has a quiz on Monday.

Extra Help: I am on duty tonight in Moore if you would like to review anything.
