How do you seperate a mixture of salt and sand using basic scientific equipment?

Question

Expain a procedure

Answer 1

One way would be to place the salt and sand mixture in a beaker and slowly add water to dissolve the salt. The water needs to agitate the sand slightly, but not throw it up high enough that it will wash out over the top of the beaker. Eventually the beaker will overflow. The overflow could be collected by placing the beaker on a stiff screen over a large funnel and channeling the water from the funnel into another beaker where the is water boiled away using a Bunsen burner, leaving the salt. After sufficient washing, the sand is drained of water and allowed to dry.

Answer 2

Here is one way.
Salt is soluble in water while sand is not.

Add some water to the salt and sand mixture in a *beaker.
Stir (* with a glass stirring rod) to dissolve the salt.
Fold a piece of *filter paper in a *funnel.
Place the funnel in a *flask big enough to hold the solution that will pass through.
Pour the solution into the funnel. The sand will remain in the filter paper. The dissolved salt will pass through.
Put the flask on a *hot plate with stirring function (with a *magnetic stirrer in the flask) and heat until almost all of the water has evaporated. Take it off the hot plate. Let the rest of the water evaporate overnight cause you do not want to crack the flask.
Voila', separated.

Answer 3

I can think of three methods. First, if the salt does not need to remain as a dry solid, add a measured amount of distilled water to dissolve the salt, drain and evaporate the water to recover the salt. In other words, rinse the salt out. Second, if the salt must remain a dry solid, then use an air stream, like sand blasting. The heavier grains will travel further and you may be able to divide it by distance traveled. Third,also if the salt must remain a dry solid, vibration. Vibration will work to raise lighter grains to "float" on top of the heavier grains. The 2nd and 3rd methods will not give a clean demarkation line between the two materials, unlike the 1st, which will. You may need to rinse the sand several times, of course, to get all of the salt to dissolve and drain out of the sand.

Answer 4

Put the mixture in a beaker. Add water to dissolve the salt. Filter the sand off. Dry the sand in an oven. Heat the remaining liquid in an evaporating dish to evaporate the water from the salt solution. Voila!

Answer 5

Measure equal amounts of salt and sand and then mix them thoroughly. Place the mixture in a pan and add water. Heat the water until all the salt dissolves. Allow the sand to settle to the bottom of the pan and then pour off the salty water. Remove the sand from the pan and put the salty water back in. Boil the water away, leaving only salt in the bottom of the pan.

Answer 6

easy, place the solution of salt & sand in warm water, (the salt will disolve in the water) seperate it with a simple coffee filter. ( the salt water will filyer thru. leaving only sand, let the water evaporate , and viola... salt is left where the water was, and the sand

Answer 7

dissolve the salt and sand mixture in water...the salt will dissolve leaving the sand to be filtered out....then just use a flame to evaporate the water leaving the salt behind

Answer 8

get a beaker mix salt with heat
