Sodium aluminate

[raivo]

Can one do anything interesting or useful with sodium aluminate? (it is byproduct of making hydrogen from NaOH, H2O and Al)

[Gilded]

Hmm... It seems to have many uses, rather uninteresting though, such as water softening. I wonder if you could isolate the sodium somehow.

[boris_73]

electrolysis would get the sodium you would have to melt it first and considering it has got aluminum in it i reckon it would have a high melting point so it would be quite hard to extract the sodium

[Gilded]

By the way, how easy it actually is to extract Na from NaCl through electrolysis? This has probably come up before, but I can't remember if there ever was an answer. :|

[boris_73]

its is quite hard to melt NaCl but if you add CaCl2 to it it will lower the temperature alot, or you could use a butane tourch but this could be quite dangerous basicaly if you can melt NaCl you can exctract sodium using electrolysis its the melting which is the hard part, plus the chlorine gas that would be given off will also be quite dangerous

[budullewraagh]

if you want sodium metal, perform electrolysis on the fused hydroxide

[boris_73]

an even simpler way to get Na is to buy it 25g for £14 at http://www.kno3.com

[Gilded]

Heh, I know that they sell K and Na in paraffin inside sealed tins (and even thought about buying some Na, or K while I'm at it). It's a rather high price though, but it's always a pleasure to throw some in your neighbor's fountain and scare the heck out of him.

[boris_73]

i thought it was quite cheap especialy considering that element web site which you told me about which costs £19 for 0.5g there is a slight difference in cost

[Gilded]

Yeah, but they are museum grade samples, in mineral oil and argon, inside a glass ampoule. The ones kno3 sells are probably a bit oxidized on the surface, and not so pure.

[boris_73]

well for cost i would rather buy the kno3 one 1 you could get the Na put in a glass ampoule with argon secondly you will have alot left to have fun with

it`s great for melting Snow too )

[boris_73]

i dont think it would just melt it

[Gilded]

Hey, why haven't I thought of that. Throw a kilo of sodium pieces around your yard and boom! No snow! No lawn either though.

[boris_73]

i guess you have alot of snow where you live because in england snow comes once in a blue moon, but hay we have alot of rain

[YT2095]

have you ever seen sodoium aluminate?

 

it`s a clear crystaline solid that`s a B!TCH to remove from electrodes, almost perfectly inert and useless except for melting snow

 

 

it will NOT explode

[boris_73]

i thought you were talking about sodium on its own not sodium aluminate

[Gilded]

Yeah me too. Good to know that snow problems can be solved with the aluminate too. Sadly, we have sometimes like 2 feet of snow so it doesn't help much unless I have like tons of it.

[boris_73]

you lucky Bast*rd i love snow and to have two feet that's one of my dream's

[Gilded]

It's fun to ride your bike to school when there's a foot-layer of snow and a 1cm layer of ice beneath it. Even more fun is the 1cm layer of ice with water on it.

[boris_73]

even better go on a pogo stick to school, apart from the embarasment you will be running with adrenalin at the thought that it could all go terribly wrong

[boris_73]

and in fact to prove how much it rains in england....its raining now its been doing it for about 1-2 hrs

[Gilded]

It has rained an incredible amount here in Finland this year, way more already than last year, so it's probably starting to be near England's rain amounts.

LOL, get used to it, I had to empty half my water butt at the garden to make room for the rain we`re gunne get, it should be here till at least 3am with plenty of local flooding.

 

I can`t say I`m unhappy about it though, it`s doing alot of work for me, incl my homemade gunpowder experiment using old methods, it saves me filling the 80 gallon drum with water )

Don't EVER say that. You do NOT want two feet of snow. It makes driving an utter bitch.......... walking a pain in the ass.......... and having to get to work next to impossible, yet you still have to show up on time. Snow is not fun once you have to drive in it.
