Problem
A student is evaluating the dissolution of NaCl(s) in water and proposes the following claims:
(A) The process is physical because no new substances appear macroscopically.
(B) The process is chemical because ionic bonds in NaCl are broken.
(C) The process involves both physical and chemical aspects because ionic bonds break and ion–dipole interactions form.
Indicate which claim(s) are fully consistent with particulate-level evidence and briefly justify your choice in one or two sentences.
