This is a reversible process.
Yes, adding salt to water is a reversible change because the salt can be dissolved in the water to create a saltwater solution, which can then be separated back into salt and water through processes like evaporation or distillation.
Sugar and Salt
it's acutely reversible
Dissolving salt in fresh water.
Dissolving salt in water is a physical change- no chemical reaction took place. If the water evaporates, the salt is still there.
It is reversible. You can allow the water to evaporate, leaving the salt behind.

Sugar and Salt
no because it is reversible. If you dissolve out the water you are left with NaCl. A change that is reversible is a physical change.
... no?If your real question is "can you separate salt from water after you've mixed the two" ... sure. One simple way is to evaporate the water, leaving the salt behind.
ice turned to water (melting) dissolving salt or sugar into water
it's acutely reversible
Dissolving salt in fresh water.
During dissolution salt is not transfotmed in another compound; also dissolution is reversible.
Sugar dissolving in water. Salt dissolving in water. Oil not dissolving in water. Ethanol dissolving in water. Carbon dioxide dissolving in soda.
Yes. The way I think about it is if you can change it back (in this case, you could filter the epsom salt out, or evaporate the water, drying it) then it is a physical change.
