How will you separate the mixture of salt, sand and iron filling?

Answer 1

water and a magnet

Answer 2

Put water in the mixture, and then filter. The filtrate or the solution you obtain is brine(salt solution). You can heat it and let the water evaoprate thus giving you the salt.

The residue or the sand and iron filling can be separated by a magnet.

Answer 3

first of all separate iron fillings with the help of a magnet. then we have a mixture of sand and salt. now dissolve this in water, wait for some time till all the salt dissolves. now filter it with the help of a filter cloth( you could use cloth as well) and separate the sand. finally, heat the salt solution till all water evaporates to get back the salt.

Answer 4

Use a magnet to attract all the iron filing in the mixture,then dilute the sand and salt with water.Filter the solution to separate the sand and water.if you want a pure water,pass the water collected through distillation.

Answer 5

Remove the iron fillings first using a magnet. After which dissolve the remaining salt and sand in water. Using filter paper, remove the sand. Then crystallise the remaining salt. wash the salt and dry it between sheets of filter paper. Then , you would have obtained a dry sample of the salt.

Answer 6

1. Iron can be separated by a magnet.
2. Salt can be separated by repeated washing with water, and decanting or filtering (and later recovered by evaporation).
3. The sand remains.

Answer 7

First- dilute the salt with water and run it through a cheesecloth so you have two parts, saltwater and other stuff.
second-dry the sand/iron as much as possible and run a magnet through it to collect the iron.
third-make salt crystals by boiling the salt water and adding as much extra salt as you can (supersaturate), and then put it in a glass and tie a string to a pencil and dangle it into the glass
That last extra step is what got me extra credit. Although it might be easier to use the magnet before you get it wet. Mine started out wet when I got it.
Good Luck!

Answer 8

this is simple grade 7 science.
spread the mixture over a paper and run a magnet over it - the iron filings will be drawn to the magnet

next, mix the salt and sand in a vile with water. pour the mixure through a fine sieve into a bowl - viola - the sand remains in the sieve (I would line the sieve with a cloth)

next, boil the water off until you have nothing left in the vile except the salt residue.

Answer 9

move magnet over the mixture. iron fillings cling to the magnet. mixture of salt and sand is left behind. add water to the residue. salt gets dissolved. filter the solution . sand is left behind on filter paper. evaporate the solution. salt is left behind as residue.

Answer 10

easy ..Water will dissolve the salt... magnet will separate iron from sand.
