Why the vanillin solution cooled in an ice bath before vacuum filtration?

it might be due to the fact that decrease in temperature result in precipitate formation. so if you cool it precipitates will form and ultimately you can easily separate out these precipitates using vaccum filteration

What will happen if a saturated solution of copper chloride is cooled?
A cooled saturated solution of copper chloride will precipitate crystals of copper chloride.
What causes the equilibrium to shift when a cooled saturated potassium nitrate solution is added to water?
When a cooled saturated potassium nitrate solution is added to water, the concentration of the potassium nitrate decreases making it less likely that he substance will precipitate out of solution.
When a hot saturated solution is cooled?
The solute will gradually form a precipitate.
What evidence do you have that the equilibrium shifted when saturated potassium nitrate solution was cooled?
The solution forms bigger crystals that have pointed ends.
What will happen when a salt solution has cooled down?
nothing unless you heated it and it starts to evaporate and cause the salt to stick to the side
What will happen if a saturated solution of copper chloride is cooled?
A cooled saturated solution of copper chloride will precipitate crystals of copper chloride.
Why must the sugar solution be cooled before adding yeast?
It's not clear in what context this question is asked, but hot water can kill yeast.
A KNO3 solution containing 45 g of KNO3 per 100g of water is cooled from 40 degrees celciuswhat will happen during cooling?
As the solution is cooled, the solubility of the solution decreases and a precipitate will form.
What would happen if a hot saturated solution was cooled quickly?
There Is No Way A Saturated Solution Can Be Cooled Quickly. But If It Did The Solution Would Desaturate.
What causes the equilibrium to shift when a cooled saturated potassium nitrate solution is added to water?
When a cooled saturated potassium nitrate solution is added to water, the concentration of the potassium nitrate decreases making it less likely that he substance will precipitate out of solution.
What would happen if a hot saturated solution was cooled slowly?
Crystallisation
When a hot saturated solution is cooled?
The solute will gradually form a precipitate.
If a hot concentrated solution is cooled some of the solute comes out of the solution what is this process called?
The process would be called evaporation.
What evidence do you have that the equilibrium shifted when saturated potassium nitrate solution was cooled?
The solution forms bigger crystals that have pointed ends.
When a saturated solution is cooled some crystals begin to appear in the solution is the solution now unsaturated?
No, the solution remains saturated. It is just that as the temperatures decreases so does the carrying capacity of the solvent.
What heppen when hot saturated solution is cooled?
Either it becomes "supersaturated" OR some material separates out (precipitates).
Why is the milk cooled before the bacteria are added?
Because it is. face it
