Using sagar to refine AgCl???

[DelayNoMore]

i just watched a video in youtube using sugar to refine AgCl to elemental Ag
http://www.youtube.com/watch?v=zJd0EnLwt44&NR=1
in the title, it's say refining AgCl to AG
but in the description, it said refing Ag2O to Ag
so actually what's he really refining?

Nothing. Converting from one form to another isn't refining, although it may improve the quality of the material in question.
There is a huge difference between refining and recovering-----just as there is a difference between melting and smelting.

so what is the video showing?
is it showing the conversiopn of Ag2O to Ag?? Is the material that he stir is silver powder?

Why not to log in on you tube and ask him directly?

He's converting silver chloride (not silver oxide) to metallic silver. What he's stirring is a mixture of silver that has already converted, plus silver chloride, that has yet to be converted. The conversion in and of itself does nothing to improve the quality of the silver, but if the silver chloride is well washed prior to conversion, one would achieve a higher level of purity. Silver is usually refined in an electrolytic cell.
