Dissolved does not mean dismantled
Sugar and salt both dissolve, but their particles separate differently.
A sugar crystal can disappear from view while its sucrose molecules remain intact.
Water separates sucrose molecules from one another without breaking the covalent bonds inside each molecule. Table salt behaves differently: its crystal separates into sodium and chloride ions. The shared word dissolving describes both changes, but it does not mean the same particles were present in the two crystals.

Behind the explanation
- American Chemical Society: Why Does Water Dissolve Sugar? ↗
Water attracts polar regions of sucrose molecules, separating whole molecules from the crystal; dissolving differs from diffusion of the dissolved material.
- American Chemical Society: Why Does Water Dissolve Salt? ↗
Sodium chloride dissolves as separated sodium and chloride ions; solubility describes how much dissolves at a specified temperature.
