Separating Salt and Water



Can a solution of salt and water be separated? If so, how?

Kirsten said...

no because the salt dissolved.

Courtney said...

Yes, by using a filter that can filter out very tiny (microscopic) pieces.

jeffrey said...

no because it will desolve

ashley said...

yes salt and water could be seperated becouse you could use a sprsial mathine but it would be to expinsive or you could wait until the water evaporate and the salt will be left over.

Aaron said...

Yes,Because the water can be evaporate
while the salt is left behind.There is also has a very expensive
pump that can separate the salt.

zack said...

yes,you can because there is a filter that they can use.

Jose said...

Water and salt can be separated by using a funnel.

jasmin said...

yes,the solution of water and salt
can be separated.

Alberto said...

A solution of salt ,water can not be separated by a paper filter ,but it can be separated by evaporating the water.

jonathon j said...

Salt and water can be separate but you have to buy or have a expensive to do.

fidel said...

Yes salt and water can be seperated in filter paper. salt and water cant be seperated in screen becase it has holes.

Macy said...

Yes a solution of salt and water can be separated through a machine or you can boil it and get the salt out or it can evaporate.

elio said...

Water and salt can be seperated.It can by evaporate the salt from the water.

Yolanda said...

Yes,a solution of salt and water can be separated. You can separate it by putting the solution in a evaporating
dish, and wait a few days for the water to evaporate.

valerie said...

yes a solution of salt and water can be separated .

Mckoy said...

yes salt and water can be separated be the water and the salt.cxdfr

Trystan F said...

yes,you can separate salt and water you can boil it and all the salt goes to the bottom.

levy said...

Yes saltwater can be separted by letingthe water dryand you can buy a filter to separted salt water.

ariana said...

porque la sal se desase con el agua.

Shelby said...

Salt and Water cannot be separated if you try to separat them it will be hard to try to separated them.

kenya said...

Yes a solution of salt and water can be separated if you put the saitwater in the filter the sait will stay in there.

cheyenne said...

Yes, a solution of salt and water
can be separated by being dried out.

Ismael said...

Yes, because if you separate it you are not going to see it.

Jose .p said...

yes, because the little paper holds
the salt and the water goes through.

Keith said...

Yes a solution could be separated by using a filter.

Adriana said...

no se puede porque la sal se ve trasparente.

devin said...

(YES) I think the salt can be separated. If the water dissolves the salt might still be there.

Kali said...

no,because if you put salt in water
you have to stir it in order for it
to be a mixture and when you stir it it will dissolve.

Austin said...

Yes,salt and water can be separated
because salt is to heavy to evaporate
with the water.

edgar said...

You can separate the salt from the water by taking the container and make sure the salt doesn't come out.

anahi said...

yes, because the salt and the water gets dry out by the light .

savanna` said...

yes,the water gets out and the salt dose NOT IT STAYS and it stays on the paper.

carmen said...

Yes,the water and salt can be separated with the filters.

jesse said...

yes, by using a filter....

Randy said...

yes because,if you stir salt and water together and then put them in light you'll see salt crystals in a few weeks.

kileymac said...

yes the salt and water can be stay to make salt water.

yessy said...

You can separate the salt from the water by taking a paper filter and making sure that only the water comes
out.

dustin said...

no because it does not have enough time to evaporate the water because
it needs time to evaporate.

Dillion said...

No,because salt dissolves when you stir the salt and water together.

Serenity said...

No a solution of salt and water can't be separated because,when you put salt in water and wait 5 or 10 minutes the salt will evaporate and even if you try to separate it the salt will still stay in the water.

Colby said...

Yes a solution of salt water can be separated.But only in certain filters .

Josh said...

Yes a solution can be separated because if you let it dissolves.

Tanner said...

yes! salt and water can be separated.
well you get a paper filter and a cup then pour!

wade said...

No, you cannot separate a solution
of salt & water because salt would have dissolved into the water.

Kiley said...

Yes,a salt water solution can be separated by using a paper filter.

Trystan said...

yes salt and water can be separated by a funall

Florinda said...

Yes, because you can separate with filter paper.

Cendy said...

No,I think salt and water can't be separated .

Kyle said...

Yes how pour thought a paper.

Ben said...

yes,i think they can be separated because you can dissolve the salt into the water and evaporate it back out.

alex said...

No i think that water can't be separated because you can dissolve the salt.

LEVI said...

NO salt and water can NOT be seporated because it is hared.

robert said...

yes, a solution of salt and water can be separated.

omar said...

No a solution of water & salt cannot be separated because the solid already dissolved into the water. DUDE!

clarissa said...

Yes, because you can separate it on filter paper

francisco said...

My answer is no.

Naomi said...

Yes because you can seethe salt.

tercy said...

yes salt and water can be separated by a paper filter.

BLANCA said...

Yes a solution of salt and water can be separated.How" YOU could put a paper filter under a cup and pour the mixture and that's how it could get separated.Also by a screen filter.

jorge said...

yes a solution of salt and water can be separated by filters.

Fhareina said...

Salt solution can be separated by the process of evaporation.Filtration cannot be used because,if you will try it there is no salt residue.While if you try to evaporate the water,some crystal drops will remain and it will solidify as salt.This is the same in getting salt in sea water.

Stephen said...

You can separate salt and water by using a ring stand, ring, evaporating dish, and a Tirrill burner. Which causes evaporation. The water changes to gas and the salt crystals are left behind. Obviously, you can separate it since it's a physical change, not a chemical change. And you cannot filter salt and water with a filter paper.

I think that the salt can be separated from the water, I am just not exactly sure how. Colors can be easily separated by using chromatography paper and there may be a similar way for salt from water, or even sugar from water, but it would be hard once the salt dissolved.

ely said...

yes it can be separate by using evaporation. the water will evaporate leaving the salt behind

Tanga said...

YES YOU CAN SEPARATE SALT FROM WATER. THERE ARE TWO DIFERENT WAYS, REVERSE OSMOSIS AND DISTILATION. GOOGLE SHOULD HELP YOU WITH EXPLANATIONS OF BOTH.

we did this at school, have a bunsen burner with a tripod ontop and a pot ontop of that which has your salt water in and then have an umbrella shaped object and a bowl under neath the tripod so when the water evaporates it hits the umbrella and the water will run down the umbrella and go into the bowl and when it has all evaporates the salt will be left as a solid in the pot!

Anastasia said...

You can actually separate them very easily by turning the salt into a crystals by mixing water with salt. You have to pour the mixture into a pan and then turn on the stove to medium so that the solution does not heat up to quickly. Then you have to wait until all of the water has evaporated. It could take from 30mins to 1hour. I don't suggest doing this with sugar because it is very hard to clean up afterwards.
Hope this helped :)

I find it funny how people not from his class are posting. Like me!
Salt can be removed from salt water either by evaporating the water (the salt is left over), or by conducting reverse osmosis.
