The reaction of sucrose with dilute HCl produces glucose and fructose. This process is known as hydrolysis, which means the breaking of a bond by the addition of water. The sucrose molecule is a disaccharide made up of one molecule of glucose and one molecule of fructose, held together by a glycosidic bond. When sucrose is hydrolyzed with dilute HCl, the glycosidic bond is broken, and glucose and fructose are formed as the products.
