My 50g Ga sample melted in summer (48C) and has stayed liquid since then - down to a chilly 5C on a winters night (how cold is that you northern hemispherians?). I have sealed it up with parafilm in a HDPE container. Developed an oxide crust after 4 months but still liquid.

When you think about it, it's just a solution. I mustn't be a true blooded alchemist cause I'd never be able to deal with the other stuff. And i think being able to obtain pure phosphorous from anything outweighs any issues I might have.

P from pee is quite easy once you know how. You need a distillation apparatus able to withstand stupidly high T. Clay is best. Above 800C the organic matter is converted to C which helps to reduce the posphates to phosphorous. During the heating process you get various distillates. Above about 600C you get a cloudy distillate coming off. This is the last one youlll see before pure white P boils over as a smoke which will condense as an oil. The receiver nees to exit into a receiver such that the end of the receiver is below the water line. White P will freeze out under the water. Mendeleev give more detail as Ive only done it once without a decent procedure.

Much better not to purify anything oneself if its available on the shelf. Disply for bone will be some powdered hydroxyapatite and pure Ca. I can demonstrate its solution on chicken bone. Urine will disply urea and uric acid. Uric acid describe as the white stuff in bird or old dog droppings. Fat will have stearic acid. Purified DNA for cell nucleus. K, Na and their salts for ion transport across membranes. Powdered keratin for nails and hair. etc. Boiled piss before, dont want to do that one again. Omega 3 oils for liver extract... The hard part is where different metals are found in the body.

This may sound weird, but some of us are interested in purifying our own elements. While trying to do the infamous P from urine extraction I got to wondering... What compounds may be extracted from urine, bones etc and how? Obvious ones are urea from urine and Ca salts from bones. I would like to set up a display of "Bodily extracts". One bored chemyst

What is the go with the oxidation states of Fe in Fe3O4? Is it mixed Fe(II), Fe(III)? Or two Fe(II.5)?

Yawn. There are plenty of net resources for this kinda thang. http://www.lyceum.org Use with respect. Some nice scientific reports. Say hi to big brother as you read, though you have nothing to hide...

*EuCl3, EuCl2 are much more soluble than the oxide. EuSO4 is sparingly soluble but commonly used to make other salts. Prep for chlorides and sulfates below. If you dont know what a reducer or amalgam are then you shouldnt be doing this chemistry. Amalgam is very toxic and I would only dispose of waste with the university. Eu2O3 + 6HCl = 2EuCl3 + 3H2O 2EuCl3 + Zn = 2EuCl2 + ZnCl2 EuCl2 + H2SO4 = EuSO4 + 2HCl 3.5g of Eu2O3 is soluble in 5.4 mL of 6M HCl to make EuCl3. Dilute this to 200 mL. Fill a Jones reductor with 1% Zn amalgam which are washed with 200 mL of 0.1M HCl. Dip the outlet of the reactor in 50 mL of 8M H2SO4 in a 600 mL beaker covered with paper. Expel air from the beaker with CO2. Pass EuCl3 slowly (2 mL/min) through the reductor. Follow with 150 mL of 0.1M HCl. Obtain light, white, hairlike crystals of unstable alpha-EuSO4. Heat this mixture to 80C in CO2 atmosphere to get stable dense crystalline beta-EuSO4 mass. Now stable under air. Filter and wash with few mLs of HCl-acidified MeOH and dry at 75C.

Tritium is used to power a permant (14 year guarantee) glow keyrings. Also in night vision scopes for guns. Where else is 3H used, and what other fun items are publicly available containing radioisotopes, other than smoke detectors?

Had to dry a reaction in chloroform. Problem was the water was acidified with HCl. Is HCl soluble in chloroform? Apparently not. When you use MgSO4 to dry acidified chloroform/water, the HCl comes out of solution. Translate - I copped a lungfull of HCl gas and have regretted it ever since. Something to do with the blood you cough up as it dissolves your bronchials.

Hopped in a car with four strangers in malaysia. to have all my money and spare clothes taken. They wanted my passport for some legit non-casino scam.

Because of its low ignition temperature - 60C, white phosphorous (which you are all most likely making) should not contact warm objects. On contact with skin it sproduces deep difficult to heal burns. Only use water to put out a P fire on the skin. Treat with a compress soaked in 1% solution of CuCO4. Never treat with salve or oil.

*GaBr3 is easy to make. Metallic Ga is heated in a stream of N2 laden with Br2 vapour. A water-clear melt forms first, becoming yellow to re-brown, due to dissolved Br2, when all the Ga hgas reacted. When the bromination is complete, the GaBr3 is distilled in an inert, Br free gas stream into a receiver and hence freed of dissolved Br2. Properties: Colourlesss, very hygroscopic crystals. MP 121.5C BP 279C OK Im using a good source for these preps. If I have tried them out, my post will begin with an *.

Molten Ga + As at room temp does nothing. I thought it might dissolve. GaAs is formed by heating Ga2O3 in a reducing stream of H2 containing As vapour. Don't even try this one in lab. Product is dark gray and brittle. MP 1238C

I have many variants of all the lanthanide salts in the cabinet in the office. I will let you know what colours I get under our UV light. Even though Europium Oxide is insoluble in water, it is not completely soluble. For fluorescence you need ver very dilute solutions anyway. Try adding a small amount of it to water, or to dilute nitric acid.

Blackout try making your Q a little clearer. Sodium methoxide is just made by reacting sodium metal or hydroxide with methanol. It is a strong, corrosive base used to make many esters. It's use is important in the formation of biodiesel where you do not want to turn fats into soaps (ie with hydroxide). c.f. http://journeytoforever.org/biodiesel_aleksnew.html for an example. It is also the most commonly used base in pharmaceutical, food, feed and chemical industries.

blood, guts and proteins. Dont shine at any celebrity faces.

Yes there is a relationship. More practically: Advise the you use plastic bottles if you want more CO2 in your brew. Add no more than one tablespoon of sugar or one barley drop per bottle. If in crowns add no more than a teaspoon as the ywould explode on a hot day. i am assuming 375 mL bottles.

A friend dragged me into his shed a few weeks ago. His grandfather used to paint Rolexes with RaCl2 containing paint. Surprise, surprise, he pulled out some lead sheet. Inside there was a vial containing approx. 5g of the stuff. I don't have a calibrated detector on me, but he wants me to have it. OK, I'm a sensible chemist and serious element collector, but what would you do with the stuff?
