Salt (sodium chloride) does not dissolve well in ethanol.

Explanation:

* Sugar (sucrose) is a polar molecule, meaning it has a positive and negative end. Ethanol is also a polar molecule. Polar molecules dissolve well in other polar molecules due to the attraction between their opposite charges.

* Salt (NaCl) is an ionic compound, meaning it consists of positively charged sodium ions (Na+) and negatively charged chloride ions (Cl-). Ethanol is not as good at solvating ions as water is because it has a lower dielectric constant. Therefore, salt does not dissolve well in ethanol.
