Electrolysis to produce red iron oxide Question
Hello everybody, I'm totally new to chemistry, but I'm trying to learn. In three months I'll be taking Chemistry I and II, so soon I'll be able to
call myself a beginner. Until then I'm doing small experiments and educating myself. Would one of you helpful and friendly chemistry guys/gals
explain to me what is happening during electrolysis. I'm using table salt and regular water. I have two old screws attached to 9 volts immersed in
this solution. I see a reaction, but what exactly is happening?
Anybody?

You are doing electrolysis not hydrolysis. On my website I'm slowly building up a database about electrosynthesis. You are making Iron II hydroxide
(dark green) which then oxidize because of dissolved oxygen into Iron III hydroxide (brown).
Reaction equations:
2Cl- - 2e- -) Cl2
2H2O + 2e- -) H2 + 2OH-
2Na+ + 2OH- -) 2NaOH
Cl2 + Fe -) FeCl2
FeCl2 + 2NaOH -) 2NaCl + Fe(OH)2
Overall:
Fe + 2e- + 2H2O -) H2 + Fe(OH)2
Oxygen oxydation:
4Fe(OH)2 + O2 + 2H2O -) 2Fe2(OH)6
If you have any other question you can ask me on the contact tab of my website or via U2U.

I never asked for this.

Ok, thank you. I know more now than I did a couple of hours ago 
Keep up with your electrosynthysis project, I am bookmarking your website.

Plante: My website (Sorry for adf.ly but I need way to get money for new chemistry equipment/reagent) :
http://adf.ly/9YqGI I can not make head or tail of this, I'm either waiting for the video to load (hours) Is this an advertising video? I can
not see any links buttons pulls levers bobbles togs or anything to find your website?
I was simply interested in your project.

Chymical Pulverization.’ (John Friend, Chymical Lectures London, 1712)

It should be easier now to access on my website, it was advertising and in the upper corner there was a skip this add button. Simply click on the link
in my signature.
I never asked for this.
