Why is it not possible to filter the sea water to obtain the salt?

Filtration only removes the insoluble substances in sea water, such as sand, micro-organisms, seaweed, etc. But it fails to remove the soluble substances, such as Sodium Chloride and other ionic compounds. Therefore, the filtrate would not be pure water, but a mixture of water and soluble impurities.

How you would obtain salt from a mixture of salt and chalk?
First you can mix the salt and chalk together in water. Then using filtration, you can filter the chalk out. Lastly, using evaporation to get salt.
What are the steps for salt water?
Add salt to water to obtain salt water.
Do you still need a sand filter with a salt water system?
no the salt will disolve....
Is it true that if salt water is poured through a filter the salt will be trapped on the filter?
true
How can separate water and salt without lossing of water?
Get a filter funnel and filter paper and pour in solution . water will run through and salt left behind
How would you get back salt from a mixture of sand and salt?
Add water and stirr: salt is soluble, sand not. Filter the solution. On the filter re- main sand, in the solution salt. After repetitive evaporations you can obtain salt as crystals.

How do you separate sand from the salt?
Put the sand and salt mixture into a beaker of water. Put more water or raise the temperature of the water until the salt completely disappears. Pour everything in the beaker onto a piece of filter paper. The sand will stay on the filter paper while the water and salt solution will pass through the filter paper. To obtain the sale, simply boil the water and the remaining solid after all the water boiled is salt.
What are the steps for salt water?
Add salt to water to obtain salt water.
How can you filter out salt by a homemade filter?
You cant filter it out. you desalinate water through evaporating the water out of the salt.
Are there any conditions to obtain salt from sea water?
You obtain salt water by letting the sea water evaporate.
Do you still need a sand filter with a salt water system?
no the salt will disolve....
What is the possibility of separating water from salt?
Repeated evaporation/crystallization is the simplest and cheapest procedure to obtain salt from sea water. Also possible: distillation, inverse osmosis, etc.
How do you separate salt and sand?
Add the salt and sand in a pan of water. Heat the water for the salt to dissolve. Strain the mixture and the sand will be left over. Afterward, heat the water until all the water is gone and only the salt is left over.
How is sand and salt seperated?
Add more water until all the salt dissolves. Filter this mixture. The sand will be on the filter. Dry this out and sand will be left. Take the salt water and evaporate the water off and dry salt will be left. Condense the water from the evaporation and water is recovered too.
How do you get salt out of the ocean?
To obtain salt water is evaporated.
Is it true that if salt water is poured through a filter the salt will be trapped on the filter?
true
