Chem 30 Notes

Nov 1- Cells! (Electochemical, Electrolytic and spontaneity)

 

Outcome:

CH30‐EC1 Investigate the chemistry of oxidation and reduction (redox) reactions. [SI, TPS]

Indicators:

e. Illustrate and label the parts of electrochemical and electrolytic cells and explain how they work, including half‐reactions, flow of ions and flow of electrons. (K, S)
f. Differentiate between electrochemical and electrolyyic cells in terms of spontaneity, direction of electron flow, energy, charge on electrodes and chemical change. (K, S)
g. Predict the electric potential and spontaneity of various redox reactions using reduction potentials. (K, S)

Overview:

Today we looked at how cells work. We looked at electrochemical (spontaneous) and electrolytic (non-spontaneous) cells. We also discussed how to use the reduction potentials to determine if a reaction will occur spontaneously.
