SALT? What is the easiest way to get water out of Epson salt solution without contaminating or changing the salt? Thanks Answered

I want to keep the Epson salt and get rid of the water. I want to use the salt again.

Define the word "change".
Evaporation will work, but using a stove top or another fast-heating method will create anhydrous epsom salt. Since magnesium sulfate is hygroscopic, it naturally absorbs water from the air to create magnesium sulfate heptahydrate, which even if it may seem dry, still contains water within the crystal structure.

Evaporation. If you don't want to capture and reuse the water, just heat the solution and the water will evaporate, leaving the Epsom salts to crystallize out. You might want to let the last little bit of water air-dry or dry in a pan in a low oven rather than on a stovetop.

When I add new water how long will it take to dissolve back to solution?

It should just take a few minutes of stirring. It will take longer if you have 1 big lump of crystal and less time if you have crumbled bits.

I use 1 part dry epsom salts to 8 parts water for soaking wounds to prevent infection. This is a saturated solution (that is all the salt the water will hold).
