Why is ice cold water rather than room temperature or warm water used to wash the remainder of the benzoic acid out of the beake
1 answer:
Filtration, is a chemical process where you are separating a precipitate from a solution.
As a general rule:
"Solubility of compounds decrease with the increasing of temperature" as you can see in the graph
Now, if you want to recover benzoic acid from an aqueous solution, the better option would be with Ice cold water because its solubility will be lower producing more precipitate.
