Q&A for How to Separate Sand and Salt

The water evaporates, leaving the salt behind.

No, there may be some salt residue left even if it is washed with water several times.

You can separate water and salt using distillation. Boil your salt water so that the water evaporates and only the salt is left.

Dissolving is combing two substances. Evaporating is separating two substances. In this lab, you would add the water so that the salt dissolves. Then once you filter the salt water, you would heat the solution to evaporate the water, leaving behind the salt.

Water will work quite well. Sand does not dissolve in water, but the salt does. Put the sand and salt mixture in a jar, then add some water. Stir the mixture until the salt is completely dissolved. Pour the salt-water solution and salt mixture in the jar onto a very fine filter. Collect the solution in a pan. Heat the pa,n and boil the solution until the water completely vaporizes. The sand should be in the filter, and the salt in the pan.

Baking soda is soluble in water. Rinse the mix with water through a filter. The sand will remain in the filter while the baking soda dissolves in the water.

If the sand and salt are mixed, it will work.

Separate the salt from the sand first. Once the salt is dry, spread it out in a thin layer. Rub a plastic ruler with a piece of 100% wool. Hold the ruler over the mixture; the static electricity will cause the pepper to cling to the ruler.

Use a coffee filter. Pour the mixture into the filter, the water will flow through, the sand will not. The salt will have dissolved into the water. If you boil the water afterwards, you can separate the salt from the water.

Because salt can be dissolved in water while remaining intact. Sand, however, cannot be dissolved in water. So, when filtered, the sand will remain behind, because the filter paper doesn't allow large particles to pass through.

You can't. The salt distillation only happens at a certain temperature.

Wear something that can insulate your hands to prevent them from getting burned. Also, ask for parental guidance when doing the experiment.

It doesn't come back but rather the water evaporates, leaving behind the salt.

It is used for separating the 2 substances together and making sure there are no lumps in the sand or the salt mixtures. The salt is separated by the strainer and both are separated from one another.

You do this so when you add the water, it will hopefully evaporate and separate. Then when you have separated it, you should get 2 separate bowls and scoop the sand into one and the salt into the other.

You can separate sand from water by letting the sand sink to the bottom. Once it's at the bottom, you can pour it in to another container.
