Why Is Sugar Soluble In Water But Not In Alcohol?

Sugar is soluble in all organic alcohols to some extent.  Both sugar and alcohol possess the hydrogen content in molecular structure that allows for bonding (the OH/hydroxy group) which also translates then to solubility through that hydrogen bonding.  But, here it can also be tricky, because put in most basic terms, sugar's solubility is also affected by the length of the molecular chain (more carbon atoms) in some alcohols.  In such cases, there are more carbons atoms in the chain, and those carbon atoms actually interfere with the hydrogen bonding between the sugar and alcohol molecules, and so negatively impacts solubility.  It is the hydrogen bonding that also is responsible for sugar's water solubility.  Obviously the H2O will not have the carbon atoms that  interfere with the hydrogen bonding, and so sugar remains highly soluble in water.

Even though water is not a universal solvent it still is one of the most powerful natural kind of solvent known to man. The reason for water being so good at dissolving things is that it bonds easily with those molecules that have some kind of electric charge. It is immaterial to water if the substance possesses a partial charge (polar molecule) or a full charge (ion). Sugar is a polar compound. It readily dissolves in water because when the molecule of sucrose breaks away from the crystal of sugar it immediately gets surrounded by molecules of water. Salt dissolves in water due to the same basic principles.

There are factors that at time increase the solubility of water. For instance temperature, higher temperatures basically increase the saturation point of water and vice versa.

Sugar is soluble due to the presence of hydroxyl groups that dissolve in water. It is due to the presence of OH groups. They are those factors that enable the breaking up of the sugar and it getting mixed with water. Sugar is the source of energy for various cells. It is the solubility of water that allows the flow or spread of energy to all parts of the body.    Solubility is defined as the ability of a solvent to dissolve the solute. In the case of sugar the temperature of the solvent i.e. Water is also important. Sugar becomes more soluble as the temperature of water increases. Thus the solubility of sugar is dependent on the temperature of water.

Sugar is considered as a molecular solid, in which the individual molecules are held together by comparatively weak intermolecular forces. As sugar dissolves in water, the weak bonds between the individual sucrose molecules are broken, and these C12H22O11 molecules are released into solution and this is true that about 1800gms of sugar can dissolve in I liter of water.

Is sugar soluble in vegetable oil?

The H-atom in alcohols and OH-atom in sugar make the sugar dissolves in alcohols but the carbon atoms in alcohols weakens their bonding,so sugar is less soluble in alcohols.

Sugar is soluble in water due to the fact that it contains poo particles in the substance, So when the sugar and water come into contact the poo particles contract , a bit like your sphincter when you do a poo, this causes the poo particles to engulf and almost swallow the sugar resulting in a disappearance of the sugar or as we know it as sugar solubility.
