GENERAL KNOWLEDGE

Detailed explanation-1: -Sugar is the most soluble chemical in water among the substances listed. Sugar has six hydroxyl groups. Sugar is made from sucrose, and its molecule is more complex and bigger than the ions in the salt. When energy is applied to polar sucrose molecules, intermolecular interactions with polar water molecules develop. More items

Detailed explanation-2: -Sucrose is a polar molecule. The polar water molecules attract the negative and positive areas on the polar sucrose molecules which makes sucrose dissolve in water. A nonpolar substance like mineral oil does not dissolve a polar substance like sucrose.

Detailed explanation-3: -For example, fructose is one of the most soluble sugars, so it blends well in beverages. Fructose also is hygroscopic, which essentially means that it is good at absorbing water.

Detailed explanation-4: -You can see that at all temperatures, many more grams of sugar dissolve than salt. The graph also shows that the solubility of sugar increases much more than the solubility of salt as the temperature of the water increases.
