Rock Salt , and Sea Salt
Only some salts have hydrates, not all. These salts contain in the formula water of crystallization.
In salts are ionic bonds.
Two common salts are sodium chloride and magnesium sulfate heptahydrate.
Salts are ionic compounds.
All salts are ionic compound.
Salts are generally products of reactions between bases and acids.
Some calcium salts are organic, some calcium salts are inorganic.
This is not mandatory: some salts are very soluble, some salts are very insoluble.
Some salts are shiny.
All salts are crystallized.
Only some salts are insoluble.
Efflorescence and deposition of salts both involve the movement of dissolved salts to the surface of a material where they form solid crystals. Efflorescence occurs when the salts are brought to the surface through evaporation of water, while deposition of salts happens when the salts are pushed to the surface through capillary action or other mechanisms. Both processes can be unsightly and can cause damage to the material over time.
