Digitals Posted June 13, 2005 Posted June 13, 2005 Is potassium nitrate reactive with any liquids i.e. alcohol or water ? Well, thx for the info
YT2095 Posted June 13, 2005 Posted June 13, 2005 it wont "react" with water, it won`t Dissolve in Alcohol. it may react with some acids, and bases of a higher electronegativity, aswell as exchange reactions with some other salts.
Primarygun Posted June 13, 2005 Posted June 13, 2005 Does it react with sodium sulphite? I guess it does. Is the reaction vigorous if a zinc metal is put into a potassium nitrate solution?
budullewraagh Posted June 13, 2005 Posted June 13, 2005 KNO3 will react with bases that have more active cations. thing is, the only one is LiOH...unless the reduction potential of Rb+ is slightly more negative than -2.924. im sure fused KNO3 will react with ethanol and zinc. just won't at room temperature
Digitals Posted June 13, 2005 Author Posted June 13, 2005 Thank's for the help, but I have one more question. I know Kn03 is used in a lot in the field of explosives. But its also used in rocket engines. On "AK's Experimental" *a web site of a memeber on sfn* Says that a mixture of Kn03+powdered "confectioners" sugar+corn syrup+ iron oxide+ proper mixing techinq you can get an quality rocket propellent. Is this true ? link to Ak's site
Digitals Posted June 13, 2005 Author Posted June 13, 2005 That's awsome ! Also I have kno3 but I need it to be very fine, mine are quite large sphears... Is there a safe way to grind the kno3 ? Like a ceramic bowl and a wooden stick? or is there a faster way ? *hehe besides buying powdered kno3*-p
YT2095 Posted June 13, 2005 Posted June 13, 2005 using Wood would be universaly stupid! a simple ball mill with 5mm shot is just fine and alot safer! and its rarely used in explosives nowadays also.
budullewraagh Posted June 13, 2005 Posted June 13, 2005 whats up with kids and potassium nitrate? don't they know that chlorates are significantly more fun?
akcapr Posted June 14, 2005 Posted June 14, 2005 oh well with a wood stick, maybe, but still unlikely
latentheat Posted June 14, 2005 Posted June 14, 2005 Chlorates are fun, but KNO3 is much easier to find. My local Lowes has it as Greenlight stump remover, $3 for one pound. I think the neighbors wonder what the thick clouds of smoke that originate from my backyard are from
H2SO4 Posted June 14, 2005 Posted June 14, 2005 with wood? friction? sparks? bam Grinding it with a wood stick would (1. not explode it and (2. would not create a spark. If it did manage to ignite, it would burn very slow. That is, if the stick had been powdered. I read in Uncle Tungsten that if you make a mix of potassium chlorate and sugar, and pour a small amount on the concrete and hit it with a hammer youll get a bang.

I had never even heard about the book until today, and I heard it mentioned twice today. That always happens to me.
H2SO4 Posted June 14, 2005 Posted June 14, 2005 i read that book, i think everyone here should read it. Great book. Yes, latentheat, this always happens to me, were i here about something, then i here about it alot. The book goes from his childhood chemistry, to more complex chem, then to radiation and light energy. Has alot of very interesting chemistry history in it also. Thats funny, i told my teacher to read it.
budullewraagh Posted June 14, 2005 Posted June 14, 2005 KClO3+sugar isnt good to start with a hammer. it isnt as likely to start reacting as if you use a drop of sulfuric acid. in fact, it's best to add a drop of H2SO4, creating very unstable chloric acid, which oxidizes the sugar. that way you can, you know, get out of there before you have moles of CO2 in your lungs
jdurg Posted June 15, 2005 Posted June 15, 2005 I was always fond of dropping a gummy bear into a test tube half-full of molten potassium chlorate. Talk about a fast reaction!
Digitals Posted June 15, 2005 Author Posted June 15, 2005 hehe ok second question, does pure K react with water ?
akcapr Posted June 15, 2005 Posted June 15, 2005 kclo+candy===> awesome. also chlorate are defnately fun, id say funner than kno3. theyre so much more powerful. found that out when my rocket exploded (it was my only oxidizer a looong time ago) and i was like 10 feet away- that god for the electrical lighter.
YT2095 Posted June 15, 2005 Posted June 15, 2005 hehe ok second question, does pure K react with water ? it will also react quite nicely with Alcohol too
Primarygun Posted June 15, 2005 Posted June 15, 2005 Acidified potassium nitrate reacts with zinc metal? I guess it will,but is the reaction very vigorous?
