Which is most insoluble in water?
Calcium carbonate is insoluble in water. This reaction forms calcium hydroxide that dissolves in water as a soda and hydrogen gas. Calcium compounds are more or less water-soluble.

Soluble fiber easily dissolves in water and is broken down into a gel-like substance in the part of the gut known as the colon. Insoluble fiber does not dissolve in water and is left intact as food moves through the gastrointestinal tract.
Is alcohol insoluble in water?
Because alcohols form hydrogen bonds with water, they tend to be relatively soluble in water. The hydroxyl group is referred to as a hydrophilic (“water-loving”) group, because it forms hydrogen bonds with water and enhances the solubility of an alcohol in water.
Is sugar is insoluble in water?
Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules.
