Rock Salt
Rock salt is salt. The difference is that rock salt is impure, literally "dirty" and not suitable for eating consumption.
You create a solution of the salt in water.
A mixture. There are two definite phases
Dissolving salt in water creates a saline solution (salty water).
Rock salt is ground, dissolved in water, the solution is filtered and this solution is refined by successivelyprocesses of crystallization/recrystallization, to obtain sodium chloride (table salt) 99,99 %; and finally this salt is iodized and some anticaking substances are added.
If a solution containing rock salt is boiled, and the solvent evaporates you will be left with rock salt as the precipitate.
The solution of the mined rock salt (NaCl) is called brine.
Cooling a salt solution will crystalize the salt presumably by lowering the solubility, allowing the solution to be filtered and pure water obtained. Drinking salt water will lead to dehydration.
you can have the water evaporate and it will leave the salt behind
because it is a science.
Sodium chloride is soluble in water and the solution is filtered.
By evaporating the water of the solution and condensing it.
1. The rock salt is grinded. 2. The grinded material is dissolved in water. 3. The liquid is filtered. 4. The solution containing sodium chloride is refinned by repeated processes of crystallization/recrystallization.
- The water is released by evaporation and an impure NaCl is obtained. - The impure NaCl is dissolved. - The solution is filtered. - The solution is refined by repeated processes of crystallization and recrystallization.
You get a salt solution.
the crystallized salt is left behind
