Hi
I sorted mine into, can change back and cannot change back. I put “dissolving salt” in can change back because when you heat the water it evaporates and leaves the salt.
Can Change back
Freezing milk
Dissolving salt
Melting ice
Melting wax
Melting chocolate



Can not Change

Fizzing sodium bicarbonate and tactic acid in solution
Evaporating perfume
Dissolving sodium
Bicarbonate
Burning chocolate
Burning candle
