Interesting/Epic Chemical Reactions?

[olenik2]

Cesium dosent actually give off much energy as many the lighter alkali metals, the energy gained from ripping off the outer electron is suprisingly low.

 

Actually, lithium is the one which gives of the most energy during the reaction, but cesium requiers far less energy to start the reaction.

 

 

 

Also, cesium is quite heavy, so it will sink to the bottom of the water, which will contain the hydrogen that will sometimes fail to ignite.

 

 

 

Francium actually wont do much more than cesium, because sheer weight of the atoms slow down the reaction, the energy given off during the reaction might be even lower than of cesium.

 

 

 

Potassium gives the most bang for the buck, because it floats, gives of much more heat, and therefore will instantly ignite the hydrogen making a big bang.

Hydrazine with hydrogenperoxide.

 

 

 

Quite powerful.

 

 

 

The reason the Lithium to cesium metals react as they do it because they want to get rid of their outer elektrons( Their highest orbit only has one), which they can do by doing a redox reaction with water creating hydrogen gas(which will be ignited because of the high temperature(Not as much with Lithium, and Natrium is a maybe situation)), and OH- ions.

 

 

 

I don't know how strong of a reductor francium is, but it cannot react with air, lol.

[i_love_burritos]

If you simply want to see something flashy, just watch a Hydrogen/Oxygen reaction.

 

 

 

Or most redox reactions. Fun to watch.

 

 

 

Burning magnesium ribbon is fun. Not too violent but "flashy"

 

 

 

:D

 

 

 

 

 

 

 

Francium !?

 

I thought there were only about 25 grams of it, naturally occuring. Very large and heavy, difficult to produce.

 

 

 

i prefer physics to chem

 

 

 

Boo, physics sucks. However biology dominates all.

 

 

 

Here's something to think about. We are close to completely filling period 7 for the Periodic Table, of which Francium is a member. If we ever manage to discover an element in period 8, the most likely one we will find first is the element after Francium in the Alkali metal group. It currently holds the systematic name Ununennium. Imagine the explosions.

 

 

 

Unless of course it has nother d-7 shell with 64 electrons ?

 

 

 

I'm not quite sure.

i dare your single celled organisms to challenge my nuclear reaction

 

 

 

although since an organism was found that actually eats radiation it might be an even match. or was it just radioactive waste?

EDIT: The numbers on the periodic table, do actually mean something...

 

Little number is atomic number, big number is mass number.

 

 

 

Hooray for TIF forums being my chem. teacher.

just take some pure water try and get as few minerals as possible and bring it to its boiling point. the water actually won't boil as there are to few particles it it to cause a reaction to the heat. the energy that would have been released by the water bubbling is then stored inside of the water. put on goggles stand back and add anything from a spoon to a pinch of sand. all the energy stored in the water is then released all at once and boom.

 

 

 

This is actually a chemical example. When you remove any minerals and make it pure water you remove the nucleosites. It's at these sites that you start to see water boil. This is why you can get water hotter than boiling in a glass container in a microwave. Then if you shake it it'll bubble.

 

 

 

Tollens reagent is pretty interesting also. Basically using reduction you form a metallic coating using tollens reagent (silver nitrate), which is actually how they used to make mirrors. In my Ochem II course only 3 of the groups managed to get the nice shine, I kept my test tube for a couple of years before I broke it.

i thought it was physic? the water boiling is caused by the movement of particles in the water that is increased when heat is applied making it bubble. not because of a chemical reaction?

I always thought that it WAS from particles moving? After all, isn't temperature a measure of the kinetic energy of surrounding atoms?

No, you can boil water at room temperature. Just lower the pressure to near 0. I'm positive you are confusing normal boiling point and specific boiling point. This is why your blood boils in space when it's -273C, and 0 atm.

Francium + hydrochloric acid. Go.

 

This.

 

 

 

Brainiac had exploding metals on it, they were exploding them in bathtubs we watched it in science. :

 

 

 

I'd love to see a Francium explosion though. Maybe the government could put it on YouTube? I bet they've got some hidden away in secret.

 

it was faked. they used high explosives for the supposed alkali explosions

[eggzs]

I would think Alkali + Halogen would harness a greater reaction than Alkali + Water.

[Dracion1]

Elephant's toothpaste is a cool and fairly harmless reaction. Iirc, you just need a group 1 iodide and hydrogen peroxide, makes bucket loads of foam.

[Boris5000]

Has there really been 40 posts on this thread without "Baking soda + vinegar"?

 

 

 

I'm ashamed.

 

 

 

Because its neither interesting nor Epic...

 

 

 

 

 

 

This is probably the most fun I've had in chemistry, and it was in year 7... Although I didn't created anything as epic as that...

 

 

 

I could now though...

 

Also what is fun, Finding out Chemical Compounds without knowing what they are... It's easy, you just find out the Cation, then the Anion and Voila! Also Ionic equations are involved but... That's English Chemistry for you.

One word; thermite. It burns at a couple THOUSAND degrees Celsius. It's a mixture of 1 cup (or whatever container you prefer) aluminum (has to be at least 95% pure aluminum) and 1 cup (exact same as aluminum) iron rust, preferrably black, but red does fine too. This is a comparatively hard thing to set off. However, magnesium would do nicely, especially if you used a long enough ribbon to be able to get the Hell away before it set off. Basically, unless if you ground both substances into a fine powder and threw in some magnesium as well, all that a thermite reaction does is make liquid iron. However, one garden flower pot full of it (it has some special substance that lets it just barely contain the reaction) can melt through damn near anything that you can think of. Think of it as a sort of lava dust. VERY fun to make. If you need to know where to get aluminum and/or iron rust (some other rust types work as well, though not as good as iron), google is your friend. Or you could try a certain link in my sig. That has a LOT of different chemical reactions in it. Have fun!

Nitrogen triiodide is easy to make, and can be set off just by touching it.

This looks fun. Two questions though; how do you make it, and how much force is behind the explosion? It might be useful in a homemade grenade type weapon, or one of a couple other ideas I have.

[cydoor]

As I'm studying chemistry in the university I've come across many cool experiments.

 

One really fun compound is dimanganeseheptoxide (Mn2O7). It easy relatively easy to make: just pour some concentrated sulfuric acid on potassium permanganate. In contact with organic compounds it ignites them and might explode at the same time.

 

 

 

I also know how to make more than 10 different high explosives, but for obvious reasons, this isn't the place to tell you how.

 

 

 

Has anyone tried producing sodium via electrolysis of molten NaCl and CaCl2 mixture. From the web I found that it requires like 20kA current and that seemed a little repulsive for me, but perhaps some of you has some experience with it at much lower currents and has produced pure sodium with a success.

Things you need:

 

 

 

-Iodine cyrstals(steal some from your school, or there might be other recipes out there to get them)

 

-Household Ammonia

 

-Glassware

 

 

 

Procedure:

 

 

 

1. If the cyrstals are large, crush them. A powder would be best.

 

 

 

2. Put a large amount of ammonia into a large glass beaker(or a cup, bowl, whatever)

 

 

 

3. Put the crushed Iodine into the ammonia.

 

 

 

4. Wait overnight.

 

 

 

5. There should be some purple cyrstals in there now. Take them out.Be careful.

 

 

 

6. The cyrstals shouldnt be to volatile, but let them dry and they will explode if you throw them against something. (Depending on howmuch is made, they could explode under their own weight or even a fly landing on it)

This looks familiar..... One moment, I'll go check something.

That sounds fun, I might get round to trying that one if I manage to get into University. I did a bit of research, and I think you're referring to this. It doesn't seem to be too difficult, actually.

 

 

 

You'd also end up with a fair amount of Chlorine gas, which you could then use in further reactions.

 

 

 

This is one of the reasons why I want to study Chemistry at Uni.

That one is actually really easy. You just need equal volumes of a weak acid, a weak alkali and a little bit of Universal Indicator. Mix a small amount of UI in both. Put the alkali in the bottom of the cylinder, and really slowly and carefully use a pipette to add the acid to the surface of the alkali, keeping the cylinder perfectly still, until it's all in. If you've done it right, you'll get diffusion, and over time you'll end up with that.
