Why the collected crystals in a recrystallization are washed with cold water rather than warm water?
Warm water would make your crystals go into solution again
Why is cold solvent used to wash crystals after the mother liquor is removed?
Usually, solvents at lower temperature can dissolve lower amount of crystals than solvents at higher temperatures. For eg. if impurity is salt then you are better off washing it at a lower temperature as salts have a good solubility even at lower temperatures and as you raise temperature your crystals will start dissolving in the warm solvent.

it all depends on which crystals you mean, salt crystals can dissolve in both hot and cold water they dissolve quicker in hot water as the hot water acts as a catalyst for this
What are cold-air clouds made of?
ice crystals
How do ice crystals for in the clouds?
the air gets cold
Do crystals grow larger in size in warm temperatures or cold temperatures?
cold temperature
What solute dissolves in a cold solvent?
sugar, salt syrup anything really because if something dissolves in a hot solvent will dissolve in cold but the hot solvent will dissolve faster because the hot particles give off more energy and the hot solvent gets evenly mixed faster then the cold solvent.im in 7th grade so dont blame me if i got it wrongb SORRY!!!!!!!!!!!!! :P----------The solubility of solids in liquids is direct proportional with the temperature; in a cold solvent the solubility is reduced.
Can you dry clothes washed in cold water?
