moondogman Posted October 25, 2011 Share Posted October 25, 2011 Im running low on my campfire color. I have HCI and copper carbonate is it as simple as mixing these filtering and drying?? How hard is it to dry? Will simple boiling work? Or does anyone know of a cheap source for copper (II) chloride? Thanks Steve Link to comment Share on other sites More sharing options...
Mumbles Posted October 25, 2011 Share Posted October 25, 2011 It's about as simple as you describe. Mix them, filter out any insoluble residue, and evaporate the liquid. I would use a slight excess of copper carbonate. The dihydrate is a blue-green color, and the anhydrous form is brown. The solid will fully dehydrate around 100-120C. I actually put some in the lab oven last night at 140C, and it looks to be perfectly dehydrated without melting. You may need to heat it a little bit to drive off all of the water depending on ambient humidity. It is deliquescent, meaning that it can absorb enough water that it dissolves itself. If you get a solid out Make sure to use glass or plastic equipment. The salt and solution will be caustic toward most metals. Link to comment Share on other sites More sharing options...
