  1. I would do some more research if I were you, before coming into possession of white phosphorus.

    Ah, my mistake, silly me, of course. How could I forget that formaldehyde is sold in 37% solutions

    My interpretation was that incompatible always meant that it would "react" in some way with the incompatibles.

    Since copper is below hydrogen in the reactivity series, would there be any reaction at all? Or would the oxidizing properties of the H2SO4 manage to slowly erode away at the copper? Also, what's the point of this? You'll eventually expose the zinc core, and it'll rapidly get eaten away
  5. You might want to look up the "Achoo syndrome" for more information.
  6. Solvated potassium and nitrate ions.
  7. Molarity, as you know, is moles / litre Molality is mass of solute / mass of solvent You use molality in calculations such as osmotic pressure, boiling point elevation, and freezing point depression.
  8. You might be thinking of manganese dioxide. Though manganese ions may catalyze the decomposition of the hydrogen peroxide somewhat.

    Yup, this is correct. Some easy rules to follow are that all metal nitrates are soluble, and most metal chlorides are soluble (with the exception of PbCl2 coming to mind most readily). Other rules like these exist, and can be found on Goggle
  10. You might want to look up a reactivity series to determine which metal will displace the other (i.e. if copper is more reactive than nickel, it will cause the nickel to precipitate out, or vice versa).
  11. Gimp, simply put, is an image editing program. Either way, the gas produced will be NO2. Gimp was used to change the colour of the smoke, it was meant as a little piece of entertainment, I suppose.
  12. The gas produced, NO2, is quite corrosive and is toxic.
  13. You most likely won't get any significant yield of KNO3 from sea water...
  14. I doubt you will find anything of value in a dollar store. Maybe a bottle of salt?
  15. I believe it is Fe in HNO3, but coloured with GiMp so that the fumes appear red
  16. Vinegar is acetic acid (trivial name), also known as ethanoic acid (by the IUPAC naming system).
  17. IIRC, ammonia and bleach will make chloramine gas, not chlorine gas.
  18. It could possibly just be smoke, or some incomplete combustion products. Note that the borate esters are mildly toxic, so I don't suggest you breathe too deeply when you are burning boric acid in an alcohol.
  19. Copper sulfate mixed with a sodium hydroxide solution will precipitate out your desired hydroxide product.
  20. Ammonia is saturated at 28% IIRC. It is very soluble in water, so you shouldn't have any problem dissolving the gas into water. Household ammonia is ammonium hydroxide, IIRC, a 5% solution.
  21. Ammonium hydroxide is simply ammonia gas dissolved in water.
  22. I wouldn't recommend eating the bicarb, your friend will know you're cheating via all the fizzing and foaming going on in your mouth As for eating direct hydroxide YT, I hope that was a joke
  23. Well, you might be using non-dried chlorine/hydrogen gas
