2017-2018 Information

1. When using ΔG = -n F ξ_cell,

*need to remember 1 V = 1 J/C so units will cancel.

2017-2018 Information

1. When using ΔG = -n F ξ_cell,

Warm-up

(Simple Redox reaction to produce solid metals including Percent yield)

Oxidation Number
Oxidation - Reduction reaction stating what is oxidized, reduced, oxidizing & reducing agent
Net ionic reactions
Percent Yield

Notes on Electrochemical Cells
- LEO the Lion goes GER
  - Explains that the species that Loses Electrons is Oxidized and species that Gain Electrons is Reduced
- AND is a FAT CAT
  - Explains that in a Galvanic (also called Voltaic cell) electron Flow from the Anode To the CAThode
Videos on Electrochemical cell
- [Bosemann Video on Electrochemistry - Overview and Discussion on Electrochemical Cell]
- [Crash Course Chemistry Video on Electrochemistry} **Try to make an Voltaic cell using this interactive webpage, [http://group.chem.iastate.edu/Greenbowe/sections/projectfolder/flashfiles/electroChem/volticCell.html Online Electrochemical Cell Flash Animation]
  - Will need to have a Standard Reduction Potential Table available

Balancing Redox reactions by Oxidation Number
Balancing Redox reactions by Half Cell method
Standard Reduction Potential table (Standard Reduction Potential Tables
- [Standard Reduction Potential Table given in AP Chemistry Exam]
- [Larger Standard Reduction Potential Table], also can be found [Zumdahl Standard Reduction Potential Table]
What volt means and relationship to energy
Electrochemistry (energy push comes from substances)

Labs: 2nd part of Making an Electrochemical Cell and Redox Titration
- Nernst Equation (energy push is also a function of [ ] of species
- Can change direction of electron flow by concentration changes (thereby energy push)

If have time, could look into fuel cell
