Is it possible to separate sugar crystals mixed with wheat flour? Can you separate powdered sugar from wheat flour in the same manner?

Dear Student,
Please find below the answer:

Yes, separation of sugar crystals mixed with wheat flour is possible. Sieving is the method used in this process. This is done by allowing the mixture of sugar and wheat flour to pass through a sieve. The fine particles of wheat flour will pass through the sieve and the sugar crystals will remain in the sieve.

Powdered sugar cannot be separated from the wheat flour. This is because the particles of both powdered sugar and wheat flour are very fine and the process of sieving cannot be performed successfully for their separation.

Hope this clears your doubt.
Regards.
