BLOCK 11: Electrochemistry

Electrochemistry

Introduction:  Do you go into a state of mini-panic when your cellphone shows only 3% charge on the battery. 

Seeing that number you likely grab the nearest charger and start reversing the reduction-oxidation reaction that is giving your device the electrical power to keep operating.

The word electrochemistry almost defines itself... electro, meaning the production of electricity and chemistry, meaning producing that electricity by chemical means.

Watch each of the following videos and write a summary of each one.
