What is the purpose of the saturated NaCl solution for washing an organic layer why not use deionized water?

The bulk of the water can often be removed by shaking or "washing" the organic layer with saturated aqueous sodium chloride. The salt water works to pull the water from the organic layer to the water layer. This is because the concentrated salt solution wants to become more dilute and because salts have a stronger attraction to water than to organic solvents. Note: sometimes a saturated aqueous solution of sodium chloride is called brine.

Why is anhydrous sodium sulfate used in organic chemistry labs?
Because of its affinity for water, anhydrous sodium sulfate is often used to dry hydrophobic solvents used in aqueous organic extractions. For example a water based sample is extracted for organic compounds using dichloromethane, or ethyl ether in a separatory funnel. The organic layer is passed through a buchner funnel holding anhydrous sodium sulfate, yielding dried solvent extract.
What is the purpose of adding NaCl solution to the soap mixture?
It is used to recrystallize R-COONa. It is used to recrystallize R-COONa. It is used to recrystallize R-COONa.
What is the purpose of ice-cold ethanol?
In an experiment to extract DNA from something like an onion or strawberry, the last step is to slowly pour ice cold ethanol into the test tube. This causes the DNA to precipitate out of the solution and white stringy material appears a the boundary of the ethanol and prepared DNA solution. The reason why it happen is because ethanol solution break down the nuclear membrane and cell membrane.
What the purpose of the ammonium acetate in the gravimetric determination of aluminum as oxinate?
The purpose of the ammonium acetate in the gravimetric determination of aluminium as oxinate is as a buffer. As more ammonium acetate is added, this caused the complex of the aluminium in the solution to precipitate after the yellow supernatant was formed. Excess ammonium acetate is needed to ensure all of the crystals precipitated out completely.

What is the purpose of washing 2-chloro-2-methylbutane with saturated sodium bicarbonate?
I think it depends on the circumstances. In my lab we used NaHCO3 to wash a mixture of n-butyl alcohol and n-butyl bromide. The NaHCO3 washed out the unwanted n-butyl alcohol in order to purify the n-butyl bromide component. In addition, the salt could be used to neutralize your organic layer.

What is the purpose of trial titration?
While titrating, it is a good idea to wash down the walls of the flask with deionized water so that all of the titrant gets into the reaction mixture. Addition of small to moderate amounts of deionized water will not change the results of your titration. Source link is given below.
