in this case, it is NaO2

your sodium had peroxide and superoxide in it then

speaking of which, i did that today (see my other thread)

actually, it very well could be, considering the possibility of me getting pneumonia tomorrow. left in the beaker was a red solution. could this be any combination of Br3 and I3 anions?

how worried should i be? i saw the gas, held my breath, put it in my window and ran im nervous as hell, as i got a sniff of it

god damn. it was red/brown/orange. i also got the characteristic hydrogen sulfide rotten egg smell

i got a red gas. smelled bad. not a good thing if it's in your room. what could this be?

yeah i know about the iodide anions helping iodine dissolve. i definitely produced a great excess of chlorine. im quite sure that the initial rush of chlorine moved the u-tube out from below the surface. oh well, i'll just use this for bio lab work and use the sulfuric acid/hydrogen peroxide way tomorrow just for comparative analysis

tonight i had the urge to make some iodine, so i did using chlorine displacement. in order to generate chlorine i distilled 300mL of bleach down to a suspension of 75mL precipitated hypochlorites and 50mL supersaturated hypochlorite solution. i then placed a funnel upside-down in this, with the funnel duct-taped to a u-tube. the tube and funnel fit perfectly. this tube went under the surface of 20mL KI solution in a crucible. i added a splash of supersaturated HCl under the funnel, put the funnel back and stepped back. immediately chlorine was evolved, going through the tube and bubbling vigorously out the other end into the solution, which instantly turned purple, showing the precipitation of iodine. i kept the crucible packed in snow to prevent the sublimation of the iodine. my product is a suspension as seen below. it appears to be a solution/suspension of I2/KI, as you can see below. i believe some of the iodide wasn't oxidized because perhaps the u-tube went above the surface after the initial rapid bubbling. any ideas for making a better apparatus next time?

natural selection

i like some classical as well. rachmaninoff has to be one of my favourite artists ever. i have he himself playing his 4 piano concertos with the philadelphia orchestra and also a bunch of solo recordings including the C# minor and G minor preludes, the elegie in E flat minor, an arrangement of liebesfreude and so on

r1dermon, everybody wants potassium nitrate at one time or another. most people want it because of some urge to make either nitric acid, black powder or smoke bombs

it's not the fact that they're good oxidizers. it's the fact that i prefer other oxidizers to them

i'd be careful of the fluorine. with regard to the bromine, what happens if you seal it in a 60mL glass bottle? of course it gains impurities, but im just curious as to what? bromine oxides???

bromine is truly an amazing element. among my favourites actually. unfortunately i have yet to make some, although that will change very soon, as the chems and labware i ordered came today:)

calcium carbide is also known as "bangsite" acetylene oxidizes quite easily, which makes it so reactive...calcium chloride is quite stable

nope i like a variety, ranging from string cheese incident and galactic to ben folds and coldplay, to davinci's notebook to the entire garden state soundtrack to jack johnson to the juliana theory to modest mouse to pink floyd to the postal service to radiohead and the walkmen

i dont find nitrates to be particularly fun but hey, that's just me

perhaps, although magnesium does not react too vigorously with water. in an ocean any heat released would be rapidly dispersed. perhaps they used calcium?

napalm is made of styrene in alkanes where the alkanes are noncyclic and have 7 or more carbon. benzene can be used in addition

speaking of greek fire, anybody have an idea as to what it is composed of? vinegar and sand can extinguish it. i found a source that mentions accounts of sulfur, pitch and burning charcoal, and then later in history the same mixture with naphtha or petroleum. as well, saltpeter and turpentine later on. supposedly the closest idea however is a mixture of sulfur, tallow, rosin, turpentine, saltpetre and crude antimony wikipedia says that the most accurate representations say that it was a liquid composed of sulfur, quicklime (CaO), and liquid petroleum. as well, they mention that magnesium was probably used

heisenberg's uncertainty principle time! so, tell me the velocity of an electron in any atom of silicon in any transistor in your computer at any moment in time and its direction at this same instant in time. make sure you tell me which specific atom this is and what instant in time you are making your recordings in

eh this isnt quantum mechanics... magnesium oxidizes easily because of its valency of 2 and its nucleus' little control of the electrons in its outermost S sublevel. you know how alkali metals react with air? this is the same thing except it is more rapid. if you ignite an alkali metal it will react vigorously as well

i'm weeping at the prospect of that happening...just look at the reducing abilities it has man! actually, i would like to see what that stuff looks like dissolved in anhydrous liquid ammonia. i saw some cesium chloride on the al-chymist awhile back; $7 for 25g. no longer sold tho :*(

dont dispose of it if you have it. PLEASE
