sugar and salt have similar appearance. why are these classified as different substances
Answers
Answer:
Explanation:While sugar and salt may look similar, they are quite different. Various sugars are naturally occurring, but the term “sugar” usually refers to sucrose, which is a disaccharide made of glucose and fructose. Similarly, there are many different kinds of salt, but the word “salt” usually refers to table salt, which is a lattice structure of sodium and chloride ions held together by hydrogen bonds.
The chemical formula of sucrose is C12H22O11, meaning that each molecule of sucrose has 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms. The atoms come from one monomer of glucose plus one monomer of fructose. These two monosaccharides are connected by a glycosidic bond. The chemical formula for table salt, otherwise known as sodium chloride, is NaCl. Knowing that sodium chloride is a salt as opposed to a molecule like sucrose, this chemical formula tells us that table salt is a lattice structure composed of sodium cations and chloride anions arranged in a 1:1 ratio. Sodium chloride is held together by hydrogen bonds as opposed to molecular bonds.
