Yes, salt (usually sodium chloride, NaCl) dissolved in water can be extracted through processes such as evaporation or crystallization. When the water evaporates, the salt can be recovered as solid crystals.
The extracted salt will retain its chemical properties, meaning it will still be sodium chloride with the same crystalline structure and characteristics as before it was dissolved. The process does not change the composition of the salt, so its properties—such as its taste, solubility, and ability to conduct electricity in solution—remain unchanged.
In summary, salt can be extracted from a water solution, and it will maintain its original properties after the extraction.
