No it is not reversible because the salt disolves and cannot come back !
This is a reversible process.
Sodium chloride is dissociated in water, forming ions Na+ and Cl-. Dissolution is a physical process because the chemical composition of salt (NaCl) remain unchanged; also the process is reversible.
When a teaspoon of salt is dissolved in a pot of water, it undergoes a physical change. The salt dissociates into its constituent ions, sodium and chloride, but its chemical structure remains unchanged. This process is reversible, as the salt can be recovered by evaporating the water. Thus, the dissolution of salt in water is a physical change rather than a chemical one.
It possible to de-salinate water.
it's acutely reversible
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.
This is a reversible process.
It is reversible. You can allow the water to evaporate, leaving the salt behind.
No, adding salt to water does not change its pH level to become more alkaline. Salt does not directly affect the pH level of water.
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.
No, adding sea salt to water does not change its pH level to become more alkaline. Sea salt is a neutral substance and does not significantly affect the pH of water.

No
The pH is unchanged.
