HOW TO MAKE IODINE(element)

where do you get H2SO4 and Potassium Iodine

This is actually the contact process, normally used in H2SO4 industry. The catalyst used is normaly vanadium pentoxide (V2O5), and flankly I don't think you can get V2O5 in stores...

Besides, direct SO3 solvation in water is extremely dangerous, being SO3 even more water-withdrawing than H2SO4 itself. It would be better to dissolve SO3 in H2SO4 and make oleum.

to make sulphuric acid,
Making Sulphuric acid
Sulphuric acid is made in three steps.

Stage 1

Sulphur is heated until it melts. The liquid sulphur is burnt in air. It reacts with oxygen from the air to make sulphur dioxide gas. Stage 2 The sulphur dioxide gas is mixed with more air and heated with a catalyst. The sulphur dioxide reacts with oxygen to make sulphur trioxide. The catalyst speeds up this reaction. Sulphur trioxide gas dissolves in water to make sulphuric acid.

A way to understand this is realizing that H2SO4 acts as an oxidizing agent, following this equation

8I(-) + SO4(2-) + 10H(+) --> 4I2 + H2S + 4H2O

So, if you want to make "clean" hydroiodic acid (HI) from an iodide salt, you need a non-oxidizing acid. Phosphoric acid is a good example (H3PO4).

H3PO4 + 3I(-) --> PO4(3-) + 3 HI

HI evolves as a gas.

bubbling chlorine through an iodine solution works quite well

dude i didnt understand, after you insert the H2SO4 you get HI acid but how did you get I2 from HI?! i know that if you add NaClO sodium hypochlorit to the HI you can get I2 crystals

yeah, I really dont like this method, I've done the chlorine bubbled through iodide salt it produces more iodine.

Nice experiment. Although nasty, this reaction is very demonstrative about redox chemistry.

For obtaining I2, there are "cleaner" procedures, like oxidizing iodide solutions with nitric acid, or with permanganate in acidic solution. It would also be plausible to bubble chlorine gas throug iodide solution.

Im not sure of the hole prodedure but you need sulfur to make it

How would you make sulfuric acid......

Yea, I hate this procedure man. It releases H2S (UGH!). Iodine is easy via H2O2-route. However, drying the iodine is hard. I prefer to just buy my iodine . 250grams for about 20 EURO.

this is the worst way to make iodine by the way.

its my most recent uploaded video,check it out.

Whats your other method ?

not this method, but my other method is very noncostlty.

Nice video, but do you think that its lucrative ?

No, Its possible, I've done it on a chemistry competition, but it isn't lucrative.
For more informations write a message to me.

sorry to say,but it would be Virtually Impossible to make sodium in your home.

I need A video to show me how to make at home pure sodium metal from NaOH

No matter if you use native NaCl?

No, it will give gaseous hydrogen chloride - colorless, fuming and corrosive gas with sharp smell (water solution is hydrochloric acid). Concentrated H2SO4 will not oxidize table salt into chlorine.

Oh thats weird. If you want chlorine, mix HCL and bleach. It will react very quickly producing a lot of chlorine gas, you should be careful. Film it and upload it to youtube if you can please =) thats how i get chlorine.

I just tested it, Sulfuric acid and hydrochloric acid both react very well with NaCl but it does not produce any chlorine that I could smell.

I guess it will work. NaCl an KI are both halides of an alkali metal. It works too with potassium bromide, so why not whit salt? :)

Thats a logical question, and the thought hadn't even crossed my mind wether it would. It seems like it should, but I doubt it. I will test it to be sure.
