16. Two students were having a disagreement about whether NaNO3 mixed with water results in a physical or chemical change. Student A claims it is a physical change because no new substance is formed and upon evaporation of the water, NaNO3 could be recovered since only intermolecular forces change during dissolution. Student B claims it is a chemical change because the ionic bonds in NaNO3, which are intramolecular, are broken by the water. This forms new ions, Nat and NO5, that affect conductivity. What would your group tell Students A and B?
