Salt can either be obtained from the sea or mined from underground salt deposits. Traditional methods extract salt from sea or ocean water by letting water evaporate and collecting the residue which is natural and rich in minerals.
all you have to do is take a container and fill it with seawater. then you boil it until it completely evaporates. the only thing left in the container will be the salt from the water because it can't be evaporated. hope this helped.
Cooking salt (sodium chloride) is a mineral, which means it is found in mines.
Another method of obtaining salt is to collect sea water, which contains salt, and evaporate the water, so that only salt is left.
Buy it from the store. But if you want to make your own table salt, your best bet is not to combine solid sodium with gaseous chlorine, but to combine Sodium Hydroxide (NaOH), a base, with Hydrochloric acid (HCl). The products of the reaction between these two liquids will produce water (H2O) and table salt (NaCl). Such always happens with an acid-base reaction; water and a salt will always be formed. The particular acid and base that react will determine the salt that is formed.
After water evaporation solid crystalline sodium chloride is obtained.
Halite is one of the most common minerals found in the crust of the earth. It is extracted by surface and below surface mining methods either by excavation or by blasting.
Ocean and sea
Even if you simply air dry the sea water, you can easily find the salt. You have many alternatives too. You can also boil the water till all the water evaporates to find the salt as a residue.
because the sea water is salt water
no, sea water is a mix of H2O, sand, salt and others. H2O (water) isn't a metal and salt isn't either
The concentration would be about the same as for sea water.
salt
You obtain salt water by letting the sea water evaporate.
By evaporating the sea water. What remains is salt.
Sea water can be used to obtain salt because water is a solvent, and sea water is generally near saturation. Because the water is full of salt, which does not evaporate, when the water evaporates, salt crystals are left behind. Essentially, you are not obtaining salt from the sea water, but removing the water from the sea salt.
Yes, it is true; this is a method to obtain salt from sea water.
Water from sea water is evaporated to obtain impure salt; after crystallization/recrystallization repeated processes pure table salt is obtained.
Sea salt is refined to obtain common, edible salt.
There are natural salt deposits that were/are mined. Before this was done salt was collected from sea water. These are the ways still used to obtain salt, but improving salt extraction technologies have made it easier to obtain large quantities.
Add salt to water to obtain salt water.
Sea water is salt water.
the water has no salt and the sea water has salt
Repeated evaporation/crystallization is the simplest and cheapest procedure to obtain salt from sea water. Also possible: distillation, inverse osmosis, etc.
Yes it is a physical change
