Formation of Silver Crystals

Formation of silver crystals around a copper coil from a silver nitrate solution.
The blue solution is due to the copper being oxidized to Cu(II+).

Is that real silver like the kind used in jewelry or is it some other kind of silver?

[littlenatnatz101]

wooow then you get little silver crystal-ly bits at the bottom!!!! its like snow!

@MUDSWAT yes but silver nitrate is expensive so you wouldnt profit

@mrfantastik7 Thanks! I looked at the numbers and it turned out that silver nitrate was the limiting reagent in my equation. My silver nitrate was only 1.4g in a 250ml beaker of water, so it had a low concentration.

[mrfantastik7]

@theworldofapple it depends on your experiment. For me, silver nitrate was in a high concentration and was in excess. But for you, it could be different.

Can someone please tell me if the copper is the limiting or excess reagent?

Thanks

Well if this is real silver then it seems the world is missing out on the concept. That this basically forming Straw into Gold, except with silver. I presume it dose not create enough silver to make a large profit at a fast rate ?

@MUDSWAT Probably a tad late reaction from me, but that is real silver ;) it's a very small quantity though as they're just flakes.

not should be no deposition??

@MUDSWAT silver in jewlery usually has stuff like nickel and stuff through it, thatl be like 99% silver, only use is for lab work

You know whats cool !! get computer and electronic boards and snip out all of the components leaving just the board and wire and soak them in a tub of 70% nitric acid (outsie downwind) you can keep removing the old boards and add new boards untill no reaction occurs any longer. the nitric acid is now silver nitrate, now follow this videos instructions on retreving your dissolved silver, what is left is mostly silver which can be melted down to ingots and sold to a jeweler !

@MUDSWAT There is only silver. Ag. but to answer your implicit question, the Ag you'd get wouldn't be pure enough to make a load of money. (not to mention that AgNO3 itself costs some money)
