Yes, it is true.
One experiment you could carry out is to dissolve both rock salt and table salt in water and compare the clarity of the resulting solutions. Rock salt typically contains more impurities than table salt, so the solution made from rock salt would likely be cloudier due to these impurities. Additionally, you could conduct a simple taste test to compare the purity of the two salts.
salt was never made from rock. Yes, salt was a rock, and it still is. Its mineral name is halite. Look it up.
NaCl or sodium chloride NaCl is table salt
Table salt is made up of smaller clumps of particles than rock salt. To dissolve, particles of the salt must come in contact with the solvent particles than rock salt, resulting in faster dissolving. (Copied from the Pure Substance & Mixtures Section of some Nelson Literacy Science Text Book) :)
table salt is made up of 3 elements that is Sodium(Na), Chlorine(Cl) and Iodine(I).
The chemcial make up of table salt hampers the melting of the ice.
Common table salt is composed of sodium and chlorine.
a gold ion
The main ingredient in table salt is sodium chloride.
Yes. It is made up of Na+ ions and Cl- ions.
Table salt is made up Sodium (Na) and Chlorine (Cl)-Sodium chloride combines to form a white crystal lattice we refer to as salt.
Table salt is obtained from rock salt (from mines) or from sea salt by refining up to 97 % NaCl or more. Common procedures include filtering of the solution and crystallization/recrystallization.
