The sand can be extracted by filtration and the salt solution left can be heated to evaporate the water and leave the salt behind
Put the mixture in water and stir. After the dissolution of salt filter the solution; sand remain on the filter, salt pass in the solution.
we use evaporation
Salt is refined by the filtration of the water solution and repeated crystallization/recrystallization processes.
After the dissolution in water the refining involve filtration and processes of crystallization/recrystallization.
no
Salt is a natural mineral found in nature. We don't exactly make it, we just purify it.
To separate salt and iodine, you can use sublimation. The iodine will sublimate at room temperature, leaving the salt behind. To purify the iodine further, you can re-sublimate it by heating it gently and collecting the vapor to form pure iodine crystals.
The refining of the impure salt involve filtration of the water solution and the purification by repeated processes of crystallization/recrystallization.
rock salt is actually salt and not any type of rock. large size salt crystals are reffered to as rock salt because it is hard like rocks. its actually jsut large salt crystals. if you are looking to purify your salt you could always heat a pot of water and disolve the rock salt in it. once no more salt will desolve you can decant the salt water (poor the clear liguid off leaving behind the other stuff) into another pot leaving behind the impurities. then boil the salt water to evaporate the water leaving behind the pure salt crystals. Actually, the way to do it is. First mix the rock salt with water. The salt will dissolve and the rocks will stay. Filter it and the salt water will go through. Evaporate it and the salt will be left.
You can separate the water from the mixture through evaporation.
your a dub butt if you belive in this stuff.
you can boil the water but keep the vapour a.k.a distill it. If you only boil it the salt will remain.
