Question

which method is used to separate out common salt and sand

Answer 1

since both salt and sand are solids,you could get a magnifying glass and tweezers and eventually pick out particles of salt and sand

Answer 2

We can separate salt and sane through the solubility test...

Process:-

Pour the salt and sand mixture into a pan.

Add water. You don't need to add a lot of water. Solubility is a property that is affected by temperature, so more salt dissolves in hot water than cold water. It's okay if the salt doesn't dissolve at this point.

Heat the water until the salt dissolves. If you get to where the water is boiling and there is still solid salt, you can add a bit more water.

Remove the pan from heat and allow it to cool until it's safe to handle.

Pour the salt water into a separate container.

Now collect the sand.

Pour the salt water back into the empty pan.

Heat the salt water until the water boils. Continue boiling it until the water is gone and you're left with the salt.
