In class on this beautiful day, we practiced some more with voltaic cells and determining which substances undergo reduction and which ones go through oxidation. When trying to figure out which one participates in which equation, there is a list of Standard Reduction Potentials in the packet we have been doing. Ms. Friedmann posted videos yesterday on moodle on calculating voltages in a voltaic cell. There should be a video of what today's lesson was on I think, but essentially today's lesson was a continuation of yesterday's lesson.
One new thing we learned today was the process of Electrolysis. We did not go over it thoroughly, but we discussed the concept in class a bit. When doing some of the voltaic cell problems, some of them ended up with a negative voltage value. This means that instead of producing electricity, it consumes it. This is electrolysis.

Homework:
- Complete the WebAssigns that are due tonight
- Finish page 7 in the packet (1pt Extra Credit = page 8)
- Bring in a citric fruit and read the Fruit Battery Lab for tomorrow (in the Unit 11 Labs folder)
Next Blogger will be.......
