Elektrolysis of sodium chloride NaCl

NaCl = (Na+) + (Cl-), then Na+H2O=NaOH + H2 and finally you get NaOH+Cl2

Are you collecting the Cl2 gas or the H2 gas?

@doomsd46 Cl2 and H2...Cl2 has been made by classic elektrolysis, but H2 has been made on this way: on minus electrode you should get Na, but Na is reacting with H2O and make NaOH+H2...and you get NaOH in glass and gas H2 on electrode....understand now ? :)

@miodje678 - Yes, I only saw one test tube, so you are only collecting one gas, I was just wondering which one. I make HCl this way. I made a system out of copper plumbing parts that feeds both gases into a heavy-duty PVC chamber, which can be removed from the system and all the connections are air tight. I remove the chamber from the system, connect an ignition coil to ignite the gases, then this is bubbled through water to make HCl acid. Also, I collect th NaOH off the electrode.

@doomsd46 yeah, and you can again make NaCl in H2O by: H2+Cl2=2HCl in test tubes and you already have NaOH in glass, and than just put HCl in NaOH and you have: HCl + NaOH= NaCl + H2O....reaction of neutralization :)

@doomsd46 ''Yes, I only saw one test tube, so you are only collecting one gas''-no, i'm collecting 2 gases but chloride is dangeorus and i put test tube....on other iz hydrogen he isn't dangeorus

and what is that? O.0

[miodje678]

this is separation NaCl to Na an molecule Cl2...

[doomsd46]

You aren't collecting 2 gases if you only have one test tube, unless you are collecting both gases in the same test tube. Hydrogen forms at one electrode, chlorine forms at the other. And hydrogen isn't dangerous?! Hydrogen isn't dangerous in the fact that if you inhale it it kills, you, but in the fact if it meets a spark, or open flame, or any ignition source, it burns explosively.

ok i did this but all i got was yellow water and a bubbling stream coming from a 9volt battery what is the yellow water and what gas is making the bubbles

[doomsd46]

So you are collecting both gases in one test tube? And yes, chlorine is extremely dangerous, I have worked at a pool, chlorine leaks kill. That is why salt is the way to go, same amount of chlorine in the water, safer way of getting dissolved.
