anyone know what h20so4 is ? I know that the h20 is water and I'm fairly sure that its an acid of some sort but no idea which one.
H2O is water. H20 would be twenty hydrogen atoms - which isn't a molecule. I'm guessing the formula was meant to be sulphuric acid as Mankz suggested. Edit: Looking at a periodic table, it's semi-plausibly a compound of osmium (H2OsO4). Depends on the context really.
Since we've got some chemists in here who seem to know more than me. Anyone know if Silver Nitrate is bad for you? I had some on my hands that wouldn't come off for a good few days, should I expect to be dead soon?
Yes, but not because of the Silver Nitrate... It just depends on what your definition of "soon" is. And if you feel lucky... punk!
IIRC (It may be something else), other than possibly turning blue/grey permanently, you'll be fine, but don't quote me. EDIT: Hurrm...*wikis* Pretty much right...
Yea silver nitrate is known to stain the skin, it is pretty corrosive, but as long as it was a small amount, and you didn't drink it, or get it in your eyes or something similar. you don't have anything to worry about.
"Silverfinger" just doesn't have the right ring to it. As an arch-villain, you 'Epic Fail' as they used to say.
Pfff, the way things are going gold finger is pretty lame. Crude Oil Finger, now that's where it's at.
Yes it's a poison, but you'd need a bit to kill you. H2SO4 is Suplphuric Acid. The H2O part is simply saying it's Hydrogen Sulphide dissolved in water to make the acid because you can dissolve it in other ionic liquids too.
oh the joys of chemistry, just come home from two hours of mixing KI with K2S2O8 along with Na2S2O3, H2O and Starch. Prizes for who can tell me what all those are!
Potassium Iodide, Potassium Sulphate, Sodium Sulphate and Starch. It goes from purple to clear iirc, then starch stains it or something.,
Close but no cigar! Potassium Peroxodisulphate is the second one (or Potassium Persulfate for short) and Sodium Thiosulphate, so pretty close. The mixture is colourless (or slightly milky due to the starch) and the amylose in the starch forms a complex with the iodine molecules (once they are formed from the iodide within the KI) which is a deep blue/black colour. Pretty good there Bindi, for A2 coursework this isn't the hardest thing of all, writing about it, however, is.
ah, chemistry AS/A2. most fun subject ever. of course, it helped that i had two great teachers, one of whom was insane, and set pretty much everything at hand on fire, including himself. twice.
Mann that sucks, of my teachers is fresh out of uni' can't teach for **** "copy out the book" "make notes on this page" every lesson. Makes you want to hang yourself! The other teacher however is great, uses a lot of analogies and looks exactly like Peter Griffin! I swear some of the chemicals I'm using at the moment though have given me some respiratory discomfort and a bit of a rash (like it said it would in my risk assessment )
reminds me of the time i snorted 10-molar HCL. as i said. fun times. (why did i become a computer scientist, again?)
Oh yea. It's been eight years since I did A level chemistry so I've forgotten it. Talk to me in organic chemistry not this analytical crap. Nice way to burn your insides with acid. Try Glacial Ethanoic Acid - that'll make cutting strong onions seem easy.
