Why was the hydrolysed fat mixture poured into a concentrated salt solution to precipitate soap?

The salt reacts with the water that would go toward acting as a solvent for the organic molecule. The inorganic salt is more "thirsty" than the organic molecule and deprives the soap of sufficient water to keep it soluble. This causes the soap to precipitate.

Why is it necessary to cool the solution to room temperature in precipitate formation?
It isn't, what is important is getting the mixture to a tempurature where the precipitate is solid, and everything else is a liquid or in solution.
Is a can of frozen juice a concentrated or dilute solution?
Concentrated solution because it is a strong solution. It has a large amount of solute which fits the definition of concentrated solution.
Why does adding a salt solution to the saponification mixture cause the salt to precipitate?
Adding salt the density of the solution increase and the soap precipitate and float; the process is called "salting out".
Is the mixture of sugar in water saturated or unsaturated?
The solution is saturated with the sugar only either a suspension or a precipitate exists.
Ways to separate mixture?
There are different ways to separate a mixture including chromatography, filtration, distillation, sublimation, solvent extraction.
What is form after the solution is in mixture?
Are you talking about precipitate
Can sugar be obtained by crystallisation?
Yes. As sugar can be charred by heat, we can't use evaporation. In crystallization, the mixture is heated until a concentrated mixture is obtained. Then the mixture is left to cool so that the excess solid particles in the mixture will precipitate out as crystals. eg. sugar from sugar solution

What type of solution is aqua regia?
Mixture of 1 part HNO3 + 3 parts HCl in concentrated aquous solution

Why does benzocaine precipitate during neutralization?
When acid is added to the reaction mixture after refluxing, the amino group is protonated, making it soluble in water. When the Na2CO3 is added, the proton is removed and the benzocaine is no longer soluble. Thus it begins to precipitate out of solution when the reaction mixture is neutralized.
What are two differences between a dilute solution and a concentrated solution of sugar water?
Dilute solution, a mixture that has only a little solute dissolved in a certain amount of solvent. Concentrated solution-one that has a lot of solute dissolved in the solvent.
Ways to separate mixture?
There are different ways to separate a mixture including chromatography, filtration, distillation, sublimation, solvent extraction.
A solid produced when two solution are mixed together is called a?
When a solid is formed from two liquids, that is called a precipitate.
What substances precipitate from a mixture of Ba Ag Cl SO4 and NO3 ions in aqueous solution?
The precipitates are of AgCl and BaSO4 because they are insoluble in water
