because hot water can dissolve the precipitate.
you have to use distilled water so that you don't add additional ions to your precipitate.
The settling percipitate can attrct ions and some dissaccociated compounds to its surface by Vanderwaal's and other forces. Washing will remove ions.
the cold water prevents the precipiate from redissolving
to easily remove the black residue or to sterilize and to be easily taken away the black precipitate.
ethanolic KOH can precipitate the impurities in solution
nope but did you no you could make crystals with washing soda No.
The purpose of water washing the organic layer is for aqueous extraction to remove impurities and or reagents that are water soluble. For instance, in reactions that utilize a small tertiary amine base or inorganic base.
Crystallization of the precipitate is advanced (aging) and the filtration is improved.
to easily remove the black residue or to sterilize and to be easily taken away the black precipitate.
For washing dishes and pans.

Usually, what you're doing is to add a reagent (acid or base, for example) so that the precipitate redissolves. That allows you to run further tests.
In a modern washing machine, the wash, rinse and spin cycles are controlled by special purpose (embedded) computers.

washing money inside a washing machine is easier than laundry service thus we can save that money for our personal purpose.
