is sieving sand from stones reversible?
Yes
sieve
reversible
Pour the mixture through a sieve. The salt and sand will fall through the sieve, leaving just the stones. Then put the sand-salt mixture in water. Stir it until the salt is completely dissolved. Then pour it through a filter. The sand will remain in the filter, and the dissolved salt will pass through.
A sieve analysis test is a procedure to separate fine material from course material by means of a series of woven or perforated surfaces. The proportion of different size particles are recorded. This record is the conclusion of the analysis. Art Gatenby agatenby@cscscientific.com

Examples: sieving of sand, sieving of flour, dimensional sorting of peas and beans, etc.
A simple method is sieving.
Irreversible
{Sand+Sawdust}------Sieving--->{Small particles: sand}+{Large particles: sawdust}
Use a sieve to remove the paper clips and small stones. Heat the remaining solution until the water evaporates (which is recovered by condensation). This will leave the salt behind.

u can put your hand and grad the paper clip.
no it is irreversible change
yes, just evaporate water and you are left with sand
you pick out the stones, secondly you have to use filtering to pick out the sand and just leave the sugar.
how do you separate aluminum washers from water
because it is reversible and no new substances are formed
