What caused these salt crystals to appear


Appear so high on the pot?

Mood: feeling a little stiff after that 2,4,5 trioxin exposure.

Evaporation of the splashing liquid from the boiling water.

The large oval crystals that have formed in the pot are more confusing though.
But they're probably hollow spheres of calcium carbonate which formed around some albumins or other organics.

Appear so high on the pot?

Why yes, you do.

Salt was added, mind you.
I just don't see how it got coated all over the sides. It didn't seem to be splashing

When the water boils, each bubble sprays a fine mist of hot solution everywhere. That gives you the crystals.

What kind of distillation would seperate the two?

A Clausen adapter?

Stirring, a normal still head and a flask properly filled should be enough to prevent much salt from coming over.

A long glass tube in the style of a fractional distillation column with some glass beads should be able to catch the mist.

exact reason why boiling heavy metal salts solution in an uncovered vessel is a bad idea for contamination.

what abromination said is right, with strong stirring big bubbles don't form ( and it doesn't bump), smaller bubbles make a smaller amount of mist, plus a normal flask already has a small neck, less mist can escape (a beaker has a big exposed surface area and not much containing power of the mist), add a short column if you are paranoid and just need to remove the solvent, or use a normal distillation setup if you want to recover everything.
now the real problem, an egg does not fit through a 24/40 joint, this could be a problem for your experiment of distilling salt water and eggs

I have to ask... Distilling salt water in the presence of eggs? Is this some sort of bizarre experiment, or are you making hard boiled eggs? Or is it both?
