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.

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.

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.
