Water is a polar molecule. you may have heard water being called H20. This is because it has two hydrogens (slightly positively charged) and one oxygen (slightly negatively charged) in a molecule. Salt/Sodium Chloride/NaCl is also polar and that is the reason why it dissolves in water. Sand doesnt because it is not a polar molecule, it is just crushed rock. Hope that helps!

What method will you use to separate salt and sand?
If you dissolve the salt and the sand in water the sand will stay beind and the salt would dissappear. But if you want the salt back you can evaporate it off, by boiling the water. (with the dissolved salt in it)
How can sand and salt be seperated?
first mix them in water. sand wont dissolve in water. so it get distilled and settle down. but salt dissolves in water. after sand gets settled, gently pour off the water. the remaining is salt solution. when its heated water get evaporated and the salt remains.
Why do you add water to the salt and sand mixture?
Assuming that you're trying to separate the sand and the salt: adding water will dissolve the salt but it will keep the sand. So the sand can be separated by filtration and then the water can be evaporated leaving behind plain salt.
Can sand and salt separate from each other?
Yes, if you run water through the mixture, the salt will dissolve and the sand won't, then let the water evaporate and the salt crystals will remain separated from the sand.
If you add sand salt and some small gravel in a jug of water will it dissolve?
The salt will dissolve. I'm not sure about the sand though. The gravel is just little pieces of rock, so it won't disslove. Try it and see if the sand dissolves, because I don't know if it does!
Which will dissolve in water salt sand or gravel?
Salt will dissolve in water
Which will dissolve faster in liquids salt or sand?
Salt will dissolve faster in liquids than sand. Salt is a solute that is able to break down and mix with the liquid, forming a homogeneous solution. Sand, on the other hand, is insoluble and will not dissolve in liquid.
How do you boil salt and sand to separate them?
Salt will dissolve in water, and the more heat you add, the more salt you can dissolve, i.e. boiling the water. Sand however, is not water soluble, therefore, it will not dissolve. Let the water boil and dissolve the salt, then drain the water over a semi-permeable cloth so the sand is trapped and the water (and salt) drains through.

A container contains a mixture of sand salt and pebbles.how can each substance be separated from the other?
To separate sand from salt and pebbles, use a sieve to filter out the larger pebbles first, then add water to dissolve the salt and separate it from the sand through filtration. To separate salt from sand and pebbles, dissolve the salt in water and then evaporate the water to obtain the salt crystals, leaving the sand and pebbles behind. To separate pebbles from sand and salt, use a sieve or filtration to separate the larger pebbles from the sand and salt mixture.
How do you separate salt sand stones and it conclusion?
salt is soluble in water. Hence, it gets dissolved. But sand does not dissolve. sand is filtered out and salt is obtained by evaporating the remaining part of mixture.
How can you separate a mixture of sand iron filings and salt?
To separate a mixture of sand, iron filings, and salt, you can use a magnet to remove the iron filings, then dissolve the salt in water and filter the sand out. Lastly, evaporate the water to obtain the salt.

What are materials used for separating salt and sand?
Water and a filter would work. Pour the salt/sand into water and the salt will dissolve. Pour the mixture into a filter and the sand will be trapped in the filter. Evaporate the water and the salt will remain.
