Add water, separate the water from the sand. Let the water evaporate.
Why do you use filter paper to separate sand from water and not salt from water?
Because the salt dissolves in the water whereas sand does not.
How can you separate sand and pebbles?
As long as the particles of sand and pebbles are of different size, you can separate them using a sieve (sifter). The smaller sand particles will pass through the sieve whereas the pebble molecules will not. This is the process that occurs in sifters sold as children's toys.
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)
What type of magnet would you use to separate sand from salt?
a normal magnet
How can you separate sand water and salt?
Separate the sand grains using a fine mesh. Separate salt from the water by using evaporation (leaving the salt crystals behind), and condensation (turning the evaporated water vapor back into a liquid).
Which methods of separation would be suitable to use to separate sand and salt?
