Question

How will you separate a mixture of common salt and sand?

Answer 1

Hint: One down to earth use of science is that it tends to be utilized to help separate one substance from another. The reasons materials might be isolated from one another is on the grounds that there is some distinction between them, like size, condition of issue, dissolvability, electrical charge, or liquefying point.

Complete answer:
We have to know that, both salt and sand are solids, you could get an amplifying glass and tweezers and in the long run choose particles of salt and sand. One strategy for isolating salt and sand depends on solvency. On the off chance that a substance is solvent, it implies it's anything but dissolvable. Salt (sodium chloride) is an ionic compound that is dissolvable in water. Sand (generally silicon dioxide) isn't.
Pour the salt and sand combination into a container.
Add water. You don't have to add a great deal of water. Dissolvability is a property that is influenced by temperature, so more salt breaks down in steaming hot water than cold water. It's alright if the salt doesn't break up now.
Warmth the water until the salt breaks down. On the off chance that you get to where the water is bubbling and there is as yet strong salt, you can add a smidgen more water.
Eliminate the skillet from warmth and permit it to cool until it's protected to deal with.
Empty the salt water into a different compartment.
Presently gather the sand.
Empty the salt water once again into the vacant dish.
Warmth the salt water until the water bubbles. Keep bubbling it until the water is gone and you're left with the salt.

Note:
Another actual detachment strategy depends on the various densities of salt and sand. At the end of the day, sand is marginally heavier than salt. On the off chance that you shake a dish of salt and sand, the salt will ultimately ascend to the top.
