Reactions of sodium and Potassium with Water

Nerd Porn ;D

This is like porn for nerds.

hey, the sodium doesnt catch fire nor the potassium does, its the hydrogen from the reaction: Na(or K) + H2O ==> NaOH(or KOH) + H2 + heat, the heat liberated from this exothermic reaction ignites the hydrogen to form H2O in the reaction: 2H2 + O2 ==> 2H2O

Blahblahblah :D

[yes4me]

thank you 5/5

[kirioucha]

lol... awesome lesson!

[ejlmp]

Not once does the lecture say the flames come from the liberated hydrogen combines with the room oxygen to form water, H2O. The potassium reacts at a higher temperature assuring the burning of liberated hydrogen.

2Na + 2H20-->2 NaOH + H2. That's reaction he failed to write, The alkaline solution comes the sodium hydroxide, lye that is good for making soap from fat of animals or plants. Many more uses than that.

this professor is very funny

[muhddzar]

you should see caesium with water... i saw a vid on it. they used a glass basin and caesium the size of a coin. The bottom of the basin blew into pieces...

[Slaer07]

pretty awesome professor, too

[BelindaFan1919]

AWESOME!!

Anyone witnessed Francium with Water?

[cautionthisissparta]

yes it was on brainiac once :p

[theultimatekoopa2]

Was it? I thought they only done Rubidium and Caesium, but said Francium was too dangerous. This was the reason I actually asked.

[cautionthisissparta]

they didnt let them khave any becaus eit is so rare and explosive. only a coupl epounds ave ever been found naturally

Less than that so you know. There is only about 23-25g of the stuff in the Earth's crust at any given time, it is radioactive, and degrades quickly, the most stable isotope has a half-life of 22 minutes.

@theultimatekoopa2 nope....hows dat???

[theultimatekoopa2]

@dhwani7294 You do realise that replying to a comment that someone made in 2007 is not a good idea, for all you know, they could have left YouTube ages ago. Luckily for you, I'm still here. And are you asking what Francium with water is like? Well that's exactly why I asked if anyone witnessed it, because I also wanted to know.

[dhwani7294]

@theultimatekoopa2 ..i have seen it on u tube...it was awesome...just lyk small home made bomb!!..

[XxdothackerxX]

>_> Yeah, but Potassium is expensive as hell. A small amount can cost you $50.

[spritemoney]

That's sweet
