A.Heat filtrate to evaporate off the solvent (water).
B.Pour salt water filtrate into an evaporating basin on a tripod over a Bunsen burner.
C.Filter to remove the insoluble sand.
D.Place the sand/salt mixture into a beaker and add water.
E.Allow basin to cool and collect salt.
F.Stir to allow the salt to dissolve in the water
A).CDFBAE
B).CDBAFE
C).DFCBAE
D).ABCDEF

Answer 1

Hint: We can say that sand is a granular material which contains finely divided rock and particles of minerals. It contains several compositions and it could be defined by its size. We know that salt is an ionic compound that is mainly composed of sodium chloride. We know that salt is a major component that is needed for life and is used for several industrial processes such as in the manufacture of polyvinyl chloride, pulp of water, and plastics.

Complete answer:
Now based on the question, we have to order the steps for the separation of sand and salt from the mixture.
We have to first take the mixture of salt and salt in a beaker, and add water to it. After the addition of water, we have to stir such that salt gets dissolved in water. We have to now filter the sand which is insoluble. The filtrate of salt water is poured into an evaporating dish that is placed on a tripod and this is kept over the Bunsen burner. We have to heat the filtrate with that solvent which is nothing but water. We have to cool the basin and then salt is collected.
So, we can write the correct order as,
The sand/salt mixture is placed into a beaker and water is added.
The salt is stirred so it is dissolved in water.
The insoluble salt is filtered and removed.
The salt water filtrate is poured into the evaporating basin on a tripod over the Bunsen burner.
The filtrate is heated for evaporation of solvent.
The basin is cooled and salt is collected.

The correct order is DFCBAE. So, we can conclude that Option (C) is correct.

Note:
In simple words, we can separate the sand/salt mixture through the process of dissolution, filtration, and evaporation. We have to first dissolve the salt in water and sand is filtered out. From the solution, we have to evaporate water and residual salt is collected.
