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.

How do you know that a chemical change is happening in the flask?
signs of a chemical reaction occurring include: -formation of a gas (bubbles) -change in color -transfer of energy (change in temperature, giving off light) -formation of a precipitate (if a solid forms out of solution)
Account for the formation of precipitate in the test for purines.?
The formation of precipitate in the test for purines is used because purines cannot be found in human DNA unless a test is performed to find their waste or byproducts. Purines cannot be tested for without boiling in alcohol to break them down.
How can temperature affect the formation of a solution?
Temperature generally creates more kinetic energy
A solid substance that is formed in a solution is called a?
if the solution has undergone a chemical reaction and a solid forms, that solid is called a precipitate.
What is half saturation test of starch?
With 2ml of starch solution 2ml of saturated ammonium sulphate solution is added. Formation of gelatinous precipitate gives confirmation of presence of starch

What does formation of a percipitate means?
The formation of a precipitate means that some sort of insoluble product is formed that "precipitates" out of solution
What is a solid in a solution?
A precipitate is a solid in a solution. The precipitate will not dissolve in the solution, it is insoluble!! The opposite of a precipitate is a solute.
How can someone predict what formation of a precipate in a chemical reaction will take place in the solution?
For solutions of ionic compounds in water, the formation of a precipitate can be predicted by noting the concentrations of each kind of ions present in the solution after it is prepared. If the solubility product constant of any possible ionic compound-forming combination of these ions is exceeded, a precipitate will eventually form. If not, no precipitate will form.
How do you know which compound it is by adding silver nitrate?
For example, adding silver nitrate solution to a solution containing halogen ions: formation of a white insoluble precipitate.
What is a precipitaion?
APEX: A compound that doesnt disolve in water

If a seed crystal was added to a supersaturated solution how would you characterize the resulting solution?
If a seed crystal was added to a supersaturated solution, the resulting solution would be a crystallized solution. The formation of solid crystals that precipitate from a solution is called crystallization.

Temperature generally creates more kinetic energy

How do you precipitate soluble complex?
Add salt to the solution. Change the temperature of the solution. Let the solvent evaporate in increase the concentration of the soluble complex. Change the pH of the solution.
