Open in App
Solution
The correct option is B molecule-ion
When a salt is dissolved in water, it dissociates in its ions. But a covalent molecule remain as such after dissolution. Because when an ionic salt dissolved in water, the positive poles of the water molecules are attracted to the anions, while the negative poles of other water molecules are attracted to the cations, so the polar water molecules "pull" the ions out of a crystal. As a result of these interactions, the ionic bonds eventually break and ions are released into the water. Thus, attraction between molecules and salt when a salt is dissolved in water molecules is molecule−ion attraction.
