Chemistry
A student has a mixture of solid sand and NaCl(aq) in a flask. To obtain solid NaCl from this mixture, the student should
(1) Remove the sand by filtration, then evaporate the water.
(2) Remove the NaCl by filtration, and then distill the liquid.
(3) Remove the sand by filtration, then use chromatography to remove the NaCl
(4) Evaporate the water, then filter the sand and salt.

Obtaining solid NaCl from a mixture of solid sand and NaCl(aq) in a flask
include removing the sand by filtration, then evaporating the water.
Filtration involves the separation of solid particles from a solution and
involves the use of the filter which collects the solid particles.
The sand and solid Nacl are separated by first filtering the sand from the
solution. The sand is collected thereby leaving the aqueous sodium
chloride.The aqueous sodium chloride is then evaporated to give rise to the
solid sodium chloride.

To obtain solid NaCl from this mixture, the student should Remove the sand by filtration, then evaporate the water we will get the solid NaCl from the mixture. ( Option 1 )
Explanation:
The mixture contains solid NaCl and sand, in which the sand gets settled down at the bottom of the container, whereas solid sodium chloride (NaCl) gets dissolved in the water.
We have to first separate the sand by means of a common purification method known as filtration.Followed by Filtration of sand we must then filtrate must contain the solution of NaCl, which can be separated by evaporating the solution.On evaporation, we will get the crystals of NaCl in the purest form.Thus we can conclude option 1 as correct answer.
