Which statement explains why sugar dissolves easily in water, but sand does not? Sugar has a greater buoyant force than sand. Sugar has a greater conductivity than sand. Sugar has a greater hardness than sand. Sugar has a greater solubility than sand.

The correct answer is Sugar has a greater solubility than sand.

Sugar will easily dissolve in water because it has a lower density than sand, therefore it has a greater solubility.

Table sugar dissolves in water because when a sucrose molecule breaks from the sugar crystal, it is immediately surrounded by water molecules. The sucrose has hydroxyl groups that have a slight negative charge. The positive charge of the oxygen found in the water molecule binds with the sugar. As the hydration shell forms around the sucrose molecule, the molecule is shielded from other sugar molecules so the sugar crystal does not reform.

Sand can't dissolve in water because the 'spaces' in between the water particles.
