YT2095 Posted June 15, 2005 Posted June 15, 2005 Acidified potassium nitrate reacts with zinc metal?I guess it will' date='but is the reaction very vigorous?[/quote'] it won`t be the KNO3 taking part in the reaction though, it`ll be the acid, and the rate of reaction will depend on the type of acid and strength. you`ll get the same reaction without the KNO3
H2SO4 Posted June 15, 2005 Posted June 15, 2005 the alkali metals react with alcohols?Whats the reaction?
jdurg Posted June 15, 2005 Posted June 15, 2005 It's analagous to the reaction with water, but instead of H-OH reacting, you get H-OR reacting. For example, in the equation 2Na + 2H2O -> H2 + 2NaOH you get sodium metal reacting with water to form hydrogen gas and sodium hydroxide. Here's the same reaction but with ethanol in place of the water. 2Na + 2EtOH -> H2 + 2NaOEt. (Et = CH3CH2-) So instead of sodium hydroxide, you get sodium ethoxide.
budullewraagh Posted June 16, 2005 Posted June 16, 2005 just a note; alkoxides are easily hydrolyzed, so unless the alcohol is dry, you won't see much alkoxide
akcapr Posted June 16, 2005 Posted June 16, 2005 hey didigtals, is ur avatar of chems u bought of of hometrainingtools?
Digitals Posted June 16, 2005 Author Posted June 16, 2005 hey didigtals, is ur avatar of chems u bought of of hometrainingtools? Lol yes it is *thanx to your site*
H2SO4 Posted June 16, 2005 Posted June 16, 2005 i see containers with united nuclear labels on them everywere on the internet.
jdurg Posted June 16, 2005 Posted June 16, 2005 just a note; alkoxides are easily hydrolyzed, so unless the alcohol is dry, you won't see much alkoxide True, and with a mixture of water and alcohol, I'm not 100% sure but I think the reaction with the water would be more favored.
YT2095 Posted June 23, 2005 Posted June 23, 2005 the water is favoured I rem making some years ago, sodium metal in 99.9% ethanol, I was only experimenting to see what it made, and THEN looked it up after I`de gotten a clear syrupy liquid. I wanted to know how to dispose of it when I found I had little to no use for it, it said NOT to mix it with water so I`de glean from that the water would be favored. I eyedroppered it down the toilet in the end, very unimpressive it was.
budullewraagh Posted June 23, 2005 Posted June 23, 2005 the hydroxide anion is more negative than any alkoxide, so hydrolysis is favored.
weldermanx Posted June 27, 2005 Posted June 27, 2005 yo anyone here know where to get a hold of ptassium nitrate.... i cant find it anywhere but online. by the way the potassium nitrate and sugar/ sucrose thing thats a great recipe for smokebombs u just need to melt the sugar and add the nitrate
weldermanx Posted June 27, 2005 Posted June 27, 2005 hell yah ..... pure potassium creates a nicepurple flame when u drop it in water
weldermanx Posted June 27, 2005 Posted June 27, 2005 i need to take back that lst post that was stupid... dont do that unless u got satisfactory ventilation the fumes are highly toxic
EL Posted June 27, 2005 Posted June 27, 2005 Did any of you try: Potassium Nitrate + Dry Glycerol + Potassium Permanganate? OR: Sodium Chlorate + Lamp Black + Sodium Permanganate? If you did not try it, then do not try it.
weldermanx Posted June 28, 2005 Posted June 28, 2005 i wouldnt advise palying with potassium permagnate u ad that to glycerin and u got a time bomb waiting to happen
