Ch19 Test

  1. Hand in F/T forms for the Chem Contests asap!
  2. Hand in ch19 Notes and review worksheet (marked, with corrections)
  3. Test!
  4. Finish Electrochemistry WS from last class (EC #4 and the handwritten page on Electrochemical Cells)

Lab 20D – Salt Hydrolysis

  1.  Prelab check!  Have all your predictions made before you do the lab.
  2. Do the lab!
  3. Choose ONE example of a salt that shows anionic hydrolysis, cationic hydrolysis, both ions hydrolyzing, neither ion hydrolyzing, and one that is amphiprotic.  Write out the hydrolysis reactions and prove whether the solution is acidic, basic, or neutral.

Strengths of Oxidizing and Reducing Agents

  1.  Hand in field trip forms and if not, get them signed asap (especially the CCC/CCO contest)
  2. Any questions from ch19 review WS?
  3. Ch19 test on friday:  about 15-20 mc and 1-2 written Q’s.
  4. Lab activity:  In groups, react Pb, Mg, Zn, and Cu with solutions that contain Pb2+, Mg2+, Zn2+, and Cu2+ ions.  Based on what reactions occur and do not occur, write reduction half reactions and rank the oxidizing and reducing agents from strongest to weakest.
  5. Do:  Electrochemistry is Reducing me to an Ox Worksheet #4
  6. Do:  Electrochemical Cell problems WS front page (hand written one)

Quantum Chemistry – Day 2

  1.  Review:  Bohr Model and Quantum Model of the atom
  2. Videos:

3.  Read p.151-155 and do #26

4.  I will be able to write electron configurations using core notation.   I will be able to write electron configurations for anions and cations.  Here is a copy of the quantum periodic table:  Quantum Periodic Table

5. Read p.156-157 and do #28-29

6. Test on sec 1 and 2 on Wed. April 5





Goodbye Thermodynamics and Hello Electrochemical Cells!

  1. Pick up field trip forms for the Chem13 News contest and/or CCC/CCO contest.
  2.  20 minute challenge question:  2006 Form B #3.
  3. Go over ch19 review worksheet.  You can mark this yourself.  The answers are posted on last day’s blog.
  4. I will be able to explain how an electrochemical cell works and calculate the amount of energy produced.  See block 2 notes here:  Electrochemistry Day 2 – Block 2 notes

Ka, Kb, and Salts

  1.  Finish calculations for Lab 20C.
  2. Go over sections  8 and 9 on the relationship between Ka and Kb and Kw.
  3. I will be able to predict whether the salt formed from a neutralization reaction will form an acidic, basic, or neutral solution.  See notes from block 1 here:  Ka, Kb, and Salts
  4. Read section 13 and do #69-73

Intro to Electrochemistry

  1.  Go over Ksp test and do corrections.
  2. The 20 Minute Challenge!  We did #1 from the 2010 AP exam and marked it out of 10.
  3. I can identify redox reactions:  what is oxidized, reduced, the oxidizing agent, and reducing agent.  See block 2 notes here: What are Redox Reactions and  Balancing Redox Reactions – Block 2 notes
  4. See chapter 19 and 20 Learning Outcomes here:  ch19 Chemical Thermodynamics Learning Outcomes and ch20 Electrochemistry Learning Outcomes
