Sugar is soluble in water.
Sugar (sucrose) is a polar molecule. The polar water molecules attract the negative and positive regions of the polar sucrose molecules, causing sucrose to dissolve in water. In contrast, a nonpolar material, such as mineral oil, does not dissolve in a polar water molecule.
This post answers two questions: why is sugar soluble in water, and is dissolving sugar in the water a chemical or physical change?

What is Solubility?
Solubility is the amount of solute that can be dissolved in a solvent at a particular temperature and pressure. It is measured in grams of solute per 100 grams of solvent. The process of dissolving is known as solvation. Solvents dissolve solutes.
Solubility is an important factor in synthesis processes. Solubility qualities, for example, are connected to the partitioning of medication molecules throughout the body between the blood and other tissues.
Water is a universal solvent due to its polarity and capacity to create hydrogen bonds, which allows it to dissolve a wide range of compounds.
Why is sugar soluble in water?
Sugar (sucrose) molecule, like water, has bonds between the oxygen and hydrogen atoms. And, similarly to water, the area near the oxygen is slightly negative, while the area near the hydrogen is slightly positive. The polar water molecules attract the negative and positive regions of the polar sucrose molecules, causing sucrose to dissolve in water.
Is dissolving sugar in water an example of a chemical or physical change?
Sugar dissolution in water is a physical change because no new substance is formed and the process is reversible, allowing water and sugar to be separated by vaporization, condensation, and crystallization.
Is sugar dissolved in distilled water?
Sugar dissolves in distilled water because distilled water is identical to tap water. The only difference between tap water and distilled water is that distilled water is deficient in calcium and other minerals.
However, the rate of sugar dissolution in distilled water may differ from that in tap water.

Frequently Asked Questions
1. Is soap soluble or insoluble in water?
Soaps are sodium or potassium salts of fatty acids that are water-soluble.
Soaps are made from fats and oils, or their fatty acids, by chemically processing them with a strong alkali.
The soap molecule’s salt end is ionic and water-soluble. When soap is mixed with water, the ionic salt end of the soap molecule attracts and dissolves in the water molecules.
2. Is oil soluble in water?
Oil does not dissolve in water, hence it is insoluble in water, yet it floats on the surface.
3. Is salt soluble or insoluble in water?
The majority of salt dissolves in water. When salt is mixed with water, it dissolves and breaks down. Salts are composed of both negative and positive ions that are held together by the force of attraction between opposite charges, often known as polarity.
