My friend got stained by silver nitrate?

He should have washed it off when it got on him! Have him see a doctor, actually.

Yeah, there's always a chance. It's passed through saliva, so your friend probably wouldn't want to risk it even if you cleaned it well.

Check your spelling.\nAssuming you're talking about Masson stain, a.k.a. Fontana-Masson stains, it'd be for melanin.  Melanin reduces ammonia-silver nitrate and turns black\nCheers.

First, comfort your wife!  Then ask the people who are staining the fence what they are using.  Most stains do not contain lead any longer--just like most paints don't contain it any more--I'm pretty sure it's illegal for the manufacturers to use lead in those types of products now, but older stains and paints may still have some lead in it.  It usually isn't harmful unless you ingest the stuff.  Just keep your kids away from the fence until it is dry and don't let them eat or handle any of the old scrapped off stain.  Clean it up as best as you can, what you can't get picked up should be washed away with water--lots and lots of water.  If it is the neighbors fence, and is totally on his property, he can do what ever he likes to it--unless you live in a neighborhood that has rules about things like that.  Check with your neighborhood home owners association about the rules for fencing.  If the fence is on your property or belongs to you--he can't be on your side unless you let him!  Honestly, it sounds to me like this neighbor could just be having a bad day--who knows.  For your own safety and that of your family, stay in your own yard, don't call the guy and call the police if the guy gets nasty again.

try Vogel's "Qualitative Inorganic Analysis", I'm pretty sure it has all the answers 4 u.\n\ndont care editions, but for 7th ed, ISBN is 0582218667\n\n****\nokey then, from Vogels\n\n1) when heated, lead nitrate decomposes to white solid lead oxide (PbO), brown gas (NO2) and oxygen gas. Brown gas decolorizes when contact with water. \n\n2) ammonia odur. ammonium compounds are all volatile towards heat and decomposes to ammonia and an acid but quickly recombine if the acid, in this case, hydrochloric acid, is a strong acid.\n\n3) anhydrate copper sulphate is white, hydrate copper sulphate is blue. I have no idea which one you actually heated. If it's anhydrate, no change; if hydrate, blue ---> white.\n\n4) blue precipitate forms initally, but resolve upon excess reagent, clear blue soln results due to the formation of copper complex [blue precipitate: Cu(OH)2*CuSO4, complex: [Cu(NH3)4]^2+]\n\n5) brown precipitates froms [Cu(OH)2], no change with excess reagents.\n\n6) metal-gray stipe (magnesium stipe) gains a redish brown color due to formation of copper metal. Possible decolorization of the soln (depends on how much magnesium u actually put in)\n\n7) volatile reaction, solid metal solves,ignitable gas is formed. (if phenolphthalein is added to water initally, soln becomes pink)

Google the term "colloidal silver". U can make it at home and it will all but eliminate the scaring. But do it now-ASAP-its OK to get it wet and let it air dry.

tell her to drink 100% purple grape juice.  It is good for kidney's and liver so it will assist with cleaning your blood. Thus turning it back to the right color.

Copper (II) nitrate, Cu(NO3)2, is dark blue.\nBarium nitrate, Ba(NO3)2, is white.\nIron (III) nitrate, Fe(NO3)3, is purple-greenish.\nLead (II) nitrate, Pb(NO3)2, is clear or white.\n\nNot sure what the orange is, but it's not one of those.

My sister had this similar problem..I told her to go to the store such as Home Depot etc and ask them for T.S.P. or Tri Sodium Phosphate..make sure you are wearing good rubber gloves and read the directions for cleaning..it works well for taking smoke stains off house walls also..then make sure any unused product is kept out of reach of children and water..this can get to be nasty stuff.

Good grief! Your 'friend' has terminal athlete's foot or a serious infection of some sort. Time to get him/thee to a dermatologist and get the problem solved. Puss! I would think that would be the 1st clue that something is more than amiss. Fungal infections can lead to dual infections in about 20 minutes (literally). Bacteria can invade fungal-damaged tissue and reek havock. I suspect the smell alone would be enough for most sufferers to take action.

Skip the dry cleaning.  That's just unhealthy anyway.  Soak the pieces in baking soda, with hot water.  You can also soak them in vinegar, but not at the same time, since that could cause corrosion.  Make sure one is completely rinsed out before you do the next soak.\n\nIf that still doesn't work (though it should), just tell your friend that these pieces were damaged accidentally and exclude them.  Or  you can just tell her the truth.  She sounds like a good friend who would understand.

I think that isolating potassium is the wrong approach.  Potassium metal reacts with atmospheric water to form KOH and hydrogen gas.  If you accidentally get water on the metal the reaction is so vigourous that the metal will catch fire, which will be dangerous.  \n\nTry a different approach.  Dissolve KCl in water and add a molar equivalence of Silver iodide, AgI, also dissolved in water..  AgCl is nearly insoluble in water (~0.9 mg/L at 10C)  and will precipitate out, leaving KI in solution.  Filter out the AgCl and evaporate the water, leaving solid KI.  \n\nThe two biggest problems starting with KNO3 are:  It will be nearly impossible to salt out the nitrate because of its high solubility in salt form, and two, many nitrate salts, particularlyof metals, are highly explosive and dangerous.  KCl is cheap and plentiful, so why not just buy some?

use peroxide.  If it bubbles and dissolves a bit, then it is blood.

hey get it checked. how long has it been since you had the accident. you have to make sure it is not infection thats making it turn green.\n\nwell if you dont have a fever then maybe then you say is plausible.
