N2 is indeed the Nitrogen molecule' date=' althought the best way to get that rather than the flame method (as that will be CO2 contaminated) is to put a peice of Sodium or Potassium in a sealed flask and wait a while (a few days should do it).

the metal will react with the O2 making the oxide and you`ll be left with reasonably pure Nitrogen (with a little Argon, totaly ignorable).

 

this will however create Negative pressure in the vessel, but the contents will be N2

 

Avoid using Lithium metal though, as that reacts with Nitrogen quite easily, and May create potentialy dangerous negative pressures that your flask cannot withstand.[/quote']

isnt sodium in salt? or does it need to be pure? and can i make any other noble gasses?

Thanks! you're awesome! but im not gonna do chlorine, because i dont want to kill myself.. lol

There have been other threads discussing this... use the search function.

ok, sorry

Yes that also works as a catalyst for the breakdown, all the methods discussed here are the only ones i know from chemistry. Weve also done it with potassium permanganate.

Thnaks man

How can i purify it? right now i only have 3% and thats not good enough so how can i purify it? oh and i dont have any non household items i can add to it so pleese dont suggest it.

Thanks for the help,

dcstegg

I can understand your confusion then from that explanation considering what you have said' date=' sorry if i seemed abit rude!

 

In the electrolysis of water, at the cathode (negative electrode) hydrogen gas (h2) is formed, and at the anode (positive electrode) oxygen gas (o2) is formed.[/quote']

 

Ohhhh, i see now. I read it wrong.

Pb is the symbol for lead.

 

What do you mean by Pb if you do not mean lead?

i didnt wwrite it i just got it off of a website and it said that... so i supose its horibly wrong.

You cant electrolyse water and expect to make lead dioxide!!

 

Before' date=' if you would like me to write an explanation, what level of chemistry are you currently at?[/quote']

 

none, i have taken no chemistry but have some understanding of it, so if that thing i thought i made stands for lead.. i didnt make it. Also, i'm in ninth grade.

 

Oh, and i didnt attempt to make lead dioxide. What i wanted, and expected was H2 and O... or is it just H and O or neither?

you could use your own blood.

Blood eh? 'slit' ahhhhhhh.... lol i read that it was posible with a potato, true or false?

thanks, oh and i want to make them because its cool.. and i can..... maybe.

i read this on a website

"A regulated DC voltage source is preferable to ordinary batteries. Use a supply with built-in current limiting- this is a feature of almost any decent power supply, but double-check just to be safe. You can start the source out at its lowest voltage setting and gradually increase the voltage until a steady, controlled electrolysis reaction is taking place. Electrolysis can force many chemical reactions to go against their "normal" (spontaneous) direction; this will occur when a certain electric potential (i.e., applied voltage) is reached. For example, an electric current can cause Pb++ ions in water to form PbO2 (solid) and H+ (aq.), a reaction which normally proceeds the other way."

i have no clue whjat either of theese are but i think i made pb02 and h+ , because there is a clear solid like stuff floating around in the container i made it in.

No it will be mainly N2

 

Try making CO2 from baking soda and vinegar

and n2 is? nitrogen something...? id like some nitrogen to if thats what it is.. but whats the 2 for? can you explain the subscript superscript and normal numbers mean when they are next to a letter like N or H wich i think are nitrogen and hydrogen.

all i know is h20 is 2 hydrogen one oxygen

will the carbon dioxide be pure when i burn a match under a glass?

i want things like oxygen, hydrogen, carbon dioxide, and any other gas that wont kill me. so what can i make and how?

im only 15 and havent even taken chemistry in science class.. but things like this intrest me allot. i realy dont know what magnesium? whatever is and io certainly dont have it. Can i use a similar process to break it down like i do with water? or what else can i do and what will be produced?

i heard it has oxygen in it or sumthing... what ways can i get either pure oxygen from it or pure hydrogen from it? i tried electrolosys with watter to get oxygen and hydrogen but its way to slow...
