When doing a recrystallization what observations would prompt you to perform a hot filtration?

I would do a hot filtering if I observed that I was facing a situation where crystallization occurs in a hot solution, but decrystalization occurs in a cold solution.

Explanation:

The hot filtration method is generally employed in solids purification processes (solids mixing), also called recrystallization purification. In general, hot filtration is associated with the vacuum filtration method.

The hot filtration method uses the principle of different solubility at different temperatures, ie a substance is hot soluble in one solvent but not soluble in the same solvent at room temperature. In the hot solvent, only one substance in the mixture dissolves completely, the other substance remains insoluble and is retained by the filter. When the filtered solution cools, the insoluble substance is separated from the solvent.

In this case, it is only favorable to use hot filtration if you observe that crystallization of a particular material occurs in a hot solution and its dissolution occurs in cold solution.

explanation:

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.
