It's been a few years since I opened up my general chemistry textbook.
Is it possible to get Barium metal by submerging a copper wire inside a supersaturated solution of barium sulfate?

In short, no. For a multitude of reasons. The first being copper is lower than barium in the electrochemical series. Secondly, any Barium
theoretically produced would react with the solvent (water). And thirdly, do you know how soluble BaSO4 is..?

Yeah Barium sulfate is probably one of the most insoluble salts that I know of. But I thought that the minuscule amount that would dissolve could
react with something.
Is there anything that would react with Barium Sulfate then?

Barium sulfate is used for upper-GI X-ray contrast...You drink about two liters. BaSO4 in...BaSO4 out.
The compound is so insoluble that it is considered non-toxic. This is one hell of a thing, condering what is thought of the metal and its soluble
salts.
