the rock salt dissolves in the water
Salt, prefferably rock salt, dissolved in warm water.
Undissolved salt is salt that has not been dissolved in water, e.g rock salt or cooking salt.
Hot water, as hot water has more Kinetic Energy that increases of the rate of the rock salt being dissolved.
"Table salt" (or edible salt, common salt, rock salt, halite) or "brine" if it is dissolved in water.
If you are trying to measure concentration of salt in water you would be measuring molarity which is moles / liter. Moles are equal to grams of salt / the MW of salt (and if you mean NaCl then the MW is 58.44 g/mol). Density is a ratio of mass to volume (mass / volume or kg/m^3)
salt when dissolved in water will become an acidic solution
You can raise a sea urchin in a salt-water aquarium. There are no fresh water sea urchins so you would need a salt-water aquarium to properly care for the urchin.

Salt dissolved in water has no appearance. Take a glass of water, sprinkle a little salt in it, stir. Salt disappears when dissolved.
Some limestones are made by precipitation of dissolved calcium carbonate. Some cherts are formed from dissolved silicates in thermal springs and evaporite minerals, such as gypsum and rock salt (halite) are formed by evaporation of water from solutions of dissolved minerals.
