Electrolysis of Water lab
"Electro" (involving electricity) + "Lysis" (to split apart) is where we use DC voltage to carry out a "decomposition" reaction.
We will set up two, very common, electrolytic processes.... and observe what happens.

- Electrolysis is very important in modern industrial processes.
- You can do a lot of interesting and profitable chemistry by inserting electrodes into compounds and running electricity through the compound at around 5-20 volts.

- Electrolysis of Water into hydrogen and oxygen gases
- Electrolytic production of sodium hypochlorite bleach from sodium chloride
