The Hw last night was the dissociations sheet.  The answers are on Moodle

Mrs. Friedmann gave a demonstration

-Water doesn't conduct electricity

-The ions in water do though,  Only if the break apart and become +s and -s

-Water with sugar does not because the sugar does not break apart 

Notes General Ideas:

-Solutions: Mixture of two or more solutions and they consist of a solute and a solvent 
               Solute is being dissolved

               Solvent is used to dissolve the solute

-The dissolving process of ionic and covalent compounds

-Conductivity Tests

-Weak vs. Strong

Look at power point on solutions on moodle for more information

HW for tonight:

Chem Think- Go to the option two=Labs=Chemical Reactions=Parcipitate lab and fill out ChemThink LabSim questions

*     We picked up worksheets at the beginning of class, check handouts folder in moodle

*     We went over the test, until 11:25 A.M.

*     Then, we took notes on

         Unit 4 Big Ideas:

         1. Some things mix with water, and some don't
         2. Some of the things that mix with water break apart, and some don't
         3. Breaking apart is called DISSOCIATION
         4. Most of the things that break apart make it so water can conduct electricity 
         5. PRECIPITATION reactions happen because something is made that does not break apart
         6. There are lots of ways to measure and calculate how much stuff is in the water, doing the reacting

*     Remember to check moodle for homework!
