Cannot concentrate the Copper Acetate(WSDTY) in this manner. Hydrochloric acid forms an azeotrope with water which will prevent you from getting it beyond about 20%. Also, the boiling point of Copper Acetate is not always higher than that of pure water. Somewhere around 25% HCl the boiling point dips below 100 degrees C and continues to fall. At 38% HCl, the boiling point of the solution is only about 48 degrees C.

The 'natural' blue color of the Copper Acetate is almost certainly some dye the manufacturer put in (to keep people from drinking it). It is interesting that the solution turned from blue to green. Was it is dark green (on the verge of becoming black) or a pale green? If you had the proper equipment, theoretically, I suppose you could purify the HCl by boiling it and condensing the vapors. But doing this does not sound like a good idea to me. It was the color of nice green grass (dark green) but i didn't add very much, like a pinch. I just got some muratic acid (31.45%) today and it looks like smoke from dry ice when you pour it out(i'm careful). The copper compound is a little lumpy, it all turned greenish tourquoise (CuOH i think), and I added some to the muric acid and i let it sit and it turned the solution a yellowish green
