I played guitar for a while. Afterwards, I washed my hands in hot water only to find that my finger tips turned light green/blue. The strings were made of copper... If the sink water contains chlorine, maybe.. Cu + Cl2 -> CuCl2 ?? which may absorb moisture to form CuCl2 * 2H2O.. Copper (II) chloride dihydrate, which is green/blue... opinions?
If I remember correctly has a high toxicity. Which oxide of copper gives the Statue of Liberty its green colour?
Yes, Fluorine is more reactive than well, just about anything really..I can't say how toxic it is though, but should form a very strong bond with the copper helping prevent it being absorbed in a reactive form. Don't lick it off though.
I recall that in the good old days, before food became industrialized and regulated by food codes ... pickle manufacturers would add copper pennies to the pickling vats. Apparently, this resulted in a bright green color in pickles.
Definitely Flourine. Its tap water right? Its definitely flourine. A lot of electrolytes, including the four halogens, F, Cl, Br, and I can be found on tap water since it isn't very clean.
