Dear /Chem/

If i was to mix potassium with nitric acid, would i get potassium nitrate?

im a bit of a novice but i think i did my equation correctly.

first off: K + HNO3 = KNO3 +H
Balanced to: 2K + 2HNO3 = 2KNO3 + H2

any help would be appreciated.

OP here, it was mainly just a theoretical thing.

but as i understand, Nitric acid can be produced from atmospheric nitrogen.
Source: http://anonym.to/?http://library.sciencemadness.org/library/books/fixation_of_atmospheric_nitrogen.pdf

And potassium con be extracted from Potassium rich soil (no source yet)

So yeah, back to my question, is my equation correct?

>> No.201628  

Yeah, the equation is correct. Also hydrogen would immediately burn because of high temperatures produced by the reaction between potassium and the acid.

And another thing. Metallic potassium can only be obtained by electrolysing potassium compounds so it's not that simple.

Does this look legit to you guys?

Iron Oxide (rust)
Carbon (ummmmm, Charcoal!)
Sodium/Potassium Carbonate (Pool neutralizer)
Nitrogen (well the Earth's atmosphere is 70% N2, so that should be fine)
Crucible (you should get one of these, but I guess you can use a tin can)
Bunsen burner (propane blowtorch)

Here's how it works:

  1. First we convert the carbonate to the ferrocyanide.
  2. Then we convert the ferrocyanide into the cyanide.

Ferrocyanide:

tl;dr. lick ling to view the boring shit.

OP here, wont the sodium or potassium carbonate bond to the free CN, is that not the purpose of adding the carbonate? I would not use this recipe nor any that I found floating around on the interweb.

If you have nothing to contribute other then "lol you are going to fail" GTFO. Chemical equations or fun stuff to prove this procedure incorrect would be nice.

50 ppm of HCN will kill some people, Do you honestly believe that every last OCN will react during the carbonate conversion? I know for a fact that some will become HCN and like I said 50 parts per million.

Use a SCUBA system. Seriously. You mentioned Rhodium's archive, Did you read what happened to a guy on there who was making BrCN ? The HCN nearly killed him. He passed the fuck out immediately and was lucky to wake up on the floor when he did, Even luckier he didn't kill all his neighbors when he fled the area as the reaction was still churning out HCN.

Hey /chem/ im looking for a cheap way to produce Flashbangs but magnesium oxide base flashbangs are fucking expensive to make an i need some to please explain if there are any cheap to create solutions i could produce as a substitue. i think something to with ammonia would do the trick but im unsure. k thanks and fuck off and annoy some /b/tards trolls.

Conversion of Methyl Ethyl Ketone to the respective peroxide

Create solution of concentrated H2SO4 and Anhydrous MgSO4

Create binary based housing to hold MEKP in one chamber with H2S04/MgSO4 in other chamber.

When the two binary components mix, they explode on contact with force related to the amounts in each binary.

The MgSO4 will react in situ to form a bright flash along with the explosion and fire.

Obviously some engineering and chemistry is required and if you can't figure it out, too bad.

MEKP suffers from severe oxygen imbalance and is likely to simply ignite instead of explode. This is advantagous when pyrolizing the Anhydrous MgSO4 through chemical means.

does anyone have any idea on how difficult it is to obtain precurser chemicals in the U.S. do you have to have I.D. and reason to purchase them or is there just restrictions on how much can be purchased at a time

>> No.195573  

If it's anything like the UK, you need to be a registered lab, and have good reason to order them, then you've got to show what you used them for (legit research) and record everytime you use them. If you're after safrole, just buy a plant and extract it yourself, its effort, but easier than setting up a legitimate pharma to get a free high. Or SOMETIMES you can buy analogues which aren't quite covered by the laws and modify them, sometimes you don't even need to modify them.

Sup /chem/

Interested in electrolytic production of chlorates and perchlorates in a home setting.

I understand that graphite is suitable for chlorate production, but flakes apart once the chlorate concentration is high enough.

What is the best method to electrolyze alkali metal chlorides to chlorates and/or perchlorates?
