Answer:
Table salt dissolving in water
Step-by-step explanation:
NaCl(s) ⟶ Na⁺(aq) + Cl⁻(aq)
Sodium chloride is an ionic solid. When it goes into solution, the ions separate from the surface of the solid. The process is called dissociation.
A is wrong. In the solution process, the molecules simply separate from the surface of the crystal.
C is wrong. When HCl dissolves in water, it forms hydronium and chloride ions. The dissolution of covalent compounds in water to produce ions is called ionization.
D is wrong. Vegetable oil does not dissolve in water.
