Can I boil away water from a copper (II) sulfate pentahydrate and water solution
« on: October 18, 2022, 11:09:04 AM »
In our crystal growing lab, our water was not distilled and we need to remove it from our solution. How would I go about removing the water? Would evaporating the water by boiling it work? I don't want to remove the water molecules and make it anhydrous.

Are you saying you want to remove water from your grown crystals? I would gently filter it (or decant it) and collect your crystals that way. Copper sulfate pentahydrate loses a lot of its bound water at pretty low temperature.

I want to recover as much solid as I can, then discard the undistilled water. So far, we are just letting it rest overnight with a paper towel on top so that the water evaporates away at a low temperature.

Just filter the crystals out.
