Your brain produces its electric currents via movements of ions. Each nerve cell can produce a voltage (around 70 mV) through differences in ion concentrations. Your thoughts are electrochemical reactions learning about electrochemical reactions.

AP16 C19 Electrochemistry Summary

Chapter19 Electrochem Textbook Condensed

	At high temperatures, the copper reacts with oxygen to form a black oxide. 2 Cu + O2 → 2 CuO Hydrogen can react with the oxygen in copper oxide reducing the copper oxide back to pure copper. CuO + H2 → Cu + H2O Red Ox of Copper
	Invisible silver ions turn into silver which oxidizes the copper metal into copper(II) ions. The copper(II) ions turn the solution blue. Silver crystals
	Copper, silver, and gold are above H+ and cannot be oxidized by 1 M strong acids. Yet silver and copper will be oxidized into their ions by nitric acid. Learn why with this explanation from the Royal Society of Chemistry.
	Molten Ionic Compounds and Electrolysis You should watch this carefully and understand it! The particulate model is excellent.
	A forced redox reaction using electrolysis
	Electrolysis of water

Voltaic Cellsvoltages only involve addition and subtraction, but deciding on which
standard voltage to add or subtract can be confusing.
Rob does a very nice job of sorting this out. It's worth watching.
