Zinc powder and potassium nitrate
will there be any reaction with zinc powder and potassium nitrate plus water?
is it violent?
actually, zinc + silver nitrate + water can react, but silver nitrate is too expensive and easily decomposed...
can AgNO3 replaced by KNO3?

if you had Zinc nitrate and potassium metal it would indeed react to leave KNO3 and zinc metal, your way around is starting with the End products
already. it shouldn`t react as there`s no driver for it.
Zinc is more reactive than silver though, and that`s why it works with your silver nitrate.
you Can use Ammonium nitrate and Zinc powder however, you`ll also need to add a little Ammonium Chloride to this also.

is it safe to use Ammonium nitrate?
somebody told me that one bag of Ammonium nitrate blown up a building in USA

Ammonium nitrate was the main ingredient of the Oklahoma City bombing but it is not an explosive unless specially prepared with another ingredient and
even then you won't be able to set it off by accident.
Anyhow, I'm not sure how vigorous zinc will react with it... best to try in very small quantities with eye protection. Sunglasses under your goggles
may be a good idea as flash powders can be extremely bright.
EDIT: I believe it was a hell of a lot more than one bag also.

It may not go quickly, but Zn metal will reduce nitrate, as KNO3 + 3Zn + 2H2O = KOH + NH4ZnO2 + 2Zn(OH)2 (well, that's almost balanced). Once the
reaction is started, the ammonia and freed potassium will corrode the zinc faster (forming zincate ions), causing a runaway reaction. This reaction
is more significant with magnesium and aluminum powders, especially in pyrotechnic compositions; zinc is less reactive and may not in fact react.
Certainly, reactive zinc metal displaces less reactive silver metal in the case of silver nitrate.

Can you provide me the equation of between water, zinc, ammonium nitrate and ammonium chloride?
and what mass ratio are they mixed with?

Ammonium Nitrate mixed with diesel fuel is a very common explosive, but needs to be set off by something like TNT to be effective. It is used a lot
when there is a lot of rock to destroy (Mining ore, building foundations, etc), and the US government even uses it in some bombs. (With a few
additives, such as AL powder) I believe they call it GX Slurry.
Don't worry though, it is no more harmful than the KNO3 you mentioned earlier.

IIRC I tried both (unactivated) Zn and Mg on conc. solutions sometime in the past;, the only reaction was on heating, and was feeble and unimpressive.
I got the impression that only traces of nitrite were formed, but then it was freely exposed to air. Much more of the nitrate was converted to
ammonia.
Why not do instead of ask?

Sheriff, your formula for ammonium nitrate is incorrect. It should be NH4NO3

From Sheriff "When it is not anhydrous it is NH4NH3
NH3NO3 + H2O = NH4NO3 + -OH"
Pardon?

What the..... ?
Ammonia is NH3, the ammonium cation is (NH4)+
The nitrate anion is (NO3)-
Hence ammonium nitrate is NH4NO3
Please go read a chemistry textbook.

A chemistry textbook? What for? If you took the ammonium cation and reacted with an alkaline Nitrate and Muraric Acid you would get
NH4 + KNO3 + HCl = KCl + H2 + NH3NO3
I think you need a lesson of chemistry theory
If you added alkaline hydroxide prior to the acid you would get :
KOH + KNO3 + NH4 + 2 HCl = 2 KCl + H2 + [OH-] + NH4NO3
As you can see my chemistry is quite perfect as there is an anhydrous reaction and a nonanhydrous reaction.
Please dont argue who is right and who is wrong as half the stuff in a highschool chemistry is incorrect which is why they dont teach half the stuff
in the textbook. The teachers avoid specific topics that are in textbooks by eductaional plans submitted to schoolboards. It is all propoganda to weed
out people who dont know what they are talking about. |
ARE YOU KIDDING ME?
Your equations are impossible! NH3NO3?! H2? There is no reaction in your first equation.
THe second equation should only be KOH +NH4(+) --> NH3 + H2O + K(+)
Excuse me, but you are the one that needs a lesson in chemistry.

This thread doesn't belong in Chemistry in General, rather in beginnings if that with some of the post quality. Sheriff, let me be nice and say: NO.

is the mixture Ammonium nitrate+Zinc powder+Ammonium Chloride have enough heat to ignite kerosene or naptha?
