Dissolution 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.
Mixing Epsom salt and ammonia would result in a physical change. It is considered physical because no new substances are formed during the mixing process.
When Epsom salt (magnesium sulfate) is dissolved in water, it dissociates into magnesium ions (Mg2+) and sulfate ions (SO4 2-). This dissociation process is a physical change, not a chemical reaction, as the chemical composition of Epsom salt remains the same.
Mixing BaCl2 and Epsom salt would be considered a physical change. This is because no new substances are formed during the process, only a physical mixing of the two compounds occurs.
The water solution of Epsom salt is neutral.
Physical
The usual reason for salt in a pool is for chlorination. Epsom salt won't work with salt/chlorine generators. BUT, you can add epsom salt to your water.
Solubilization of salt in water is a physical change.
Solubilization of salt in water is a physical change.
No, sea salt and Epsom salt are different types of salts. Sea salt is derived from evaporated seawater and contains minerals like magnesium and potassium. Epsom salt, on the other hand, is a mineral compound of magnesium and sulfate.
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
