  1. Getting the Elements

    I found this about osmium isolation: Isolation: it would not normally be necessary to make a sample of osmium in the laboratory as the metal is available, at a price, commercially. The industrial extraction of osmium is complex as the metal occurs in ores mixed with other metals such as ruthenium, rhodium, palladium, silver, platinum, and gold. Sometimes extraction of the precious metals such as iridium, rhodium, platinum and palladium is the main focus of a partiular industrial operation while in other cases it is a byproduct. The extraction is complex because of the other metals present and only worthwhile since osmium is useful as a specialist metal and is the basis of some catalysts in industry. Preliminary treatment of the ore or base metal byproduct is required to remove silver, gold, palladium, and platinum. The residue is melted with sodium bisulphate (NaHSO4) and the resulting mixture extracted with water to give a solution containing rhodium sulphate, Rh2(SO4)3. The insoluble residue contains the osmium. The residue is melted with Na2O2 and extracted into water to extract the ruthenium and osmium salts (including [RuO4]2- and [OsO4(OH)2]2-). The residue contains iridium oxide, IrO2. Reaction of the salt with chlorine gas gives the volatile oxides RuO4 and OsO4. The osmium oxide is dissolved by treatment with alcoholic sodium hydroxide to form Na2[OsO2(OH)4], and the osmium precipiated out as pure OsCl2O2(NH3)4 by treatment with NH4Cl. Evaporation to dryness and burning under hydrogen gas gives pure osmium.

    Why is there a --------------------------------------------------------------------------------------? And also, osmium is safe in a lump.
  3. Some fun with Gallium.

    I held some molten gallium in my hand and my friend was like: 'OMG DUDE ISN'T THAT MERCURY?! DON'T YOU KNOW HOW POISONOUS THAT IS AAAAHHHHHHHH!!!' And elemental mercury won't kill you if you poke it... I hope.

    Great list. I went to Home Depot but there was no Indalloy solder. :/
  5. Some fun with Gallium.

    I have gallium. (10 g)
  6. I just recently got selenium for my element collection but I'm afraid to take it out of the bag because I've heard about selenium toxicity. I know its deadly if you ingest it but is it OK to touch it?

Phosphorus (Matchboxes) Titanium (Metallium) Chromium (Chrome-plated drill bits) Iron (From cereal ) Nickel (Pre-1980 Canadian dimes) Copper (Metallium) Zinc (Metallium) Gallium (Ebay) Molybdenum (Metallium) Rhodium (Plated ring) Silver (Metallium) Antimony (Smart-Elements) Cesium (Smart-Elements) Praseodymium (Metallium) Erbium (Metallium) Tantalum (Capacitors) Tungsten (Lightbulb) Gold (Ring) Mercury (Thermometer) Lead (Metallium) Bismuth (Metallium) Americium (Smoke detector) ? Getting soon: Tin Helium Argon Manganese Vanadium Magnesium
  10. Hydrogen gas

    If I put Iron in water, will it make hydrogen gas? Since rust is oxide, does it remove the O in water, leaving H2? I want hydrogen for my element collection! PS Call me dumb, I don't care. I just want an answer.

    Im teiu88 hi
  12. Is it legal?

    Is it legal to take Americium 241 from an ionization smoke detector? I want it for my element collection.
