> [@SCSimmons](#): > > It is. Until the water is saturated (and the salt starts piling up on the bottom, displacing water), the volume of the water the salt is dissolved in doesn’t measurably change … That is not true at all, IIRC my chemistry. While the total volume of the two components will be greater than the volume of the mixture, it is incorrect to assert that the solvent will displace **no** volume. Keep in mind that solutions don’t have to be liquid… ---
