it's acutely reversible
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.
A match burning is a chemical change. Salt dissolving in water is a physical change.
Dissolving salt in water is a physical change- no chemical reaction took place. If the water evaporates, the salt is still there.
Yes, salt dissolving in water is a physical change because it does not involve a change in the chemical composition of the salt. The salt molecules are simply dispersed in the water, but they remain the same chemical substance.
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.

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.
During dissolution salt is not transfotmed in another compound; also dissolution is reversible.

Salt dissolving in water is a chemical change, the white residue is left when the water gets saturated by the salt and the salt starts to come out of solution to gain equilibrium. The residue can also be left behind when boiling off the water.
Dissolving tablets is a physical change, as they can be distilled out again.
Dissolving Skittles in salt and water is a physical change. The Skittles are still the same chemical compounds, but they are now dispersed throughout the water-salt solution.
Dissolving is a physical process.
