Answer (1 of 2): In chemistry, there are physical properties and chemical properties. But the distinction between physical and chemical change can be misleading and confusing at times. Dissolving a Chemical or Physical Change. dissolving salt into water. Answer (1 of 13): As the other answers have correctly put it, you're looking at a case of nitpicking over terminology: the ionic bonds holding together Na and Cl ions are considered strong enough to be chemical bonds, while the hydrogen bonds holding together sugar molecules are not considered st. 25 terms . PLAY. Here's why: A chemical change produces new chemical products. In order for sugar in water to be a chemical change, something new would need to result. Dissolving sugar in water is an example of a physical change. Physical changes do not alter the identity of a substance. In contrast, dissolving a covalent compound like sugar does not result in a chemical reaction. Some people claim that this is a chemical change, since the ionic compound of sodium chloride has separated into ions of . It has not combined with the water to cause a chemical reaction. Chemistry ch. 42 terms. STUDY. Solubility is a physical property. tearing a piece of paper. Dissolving a solid in liquid, such as table salt in water, is a physical change because only the state of the matter has changed. So Option B is a correct option. Dissolving sugar in water is an example of a physical change.In order for sugar in water to be a chemical change, something new would need to result.A chemical reaction would have to occur. Physical changes can often be reversed. The reactant (sodium chloride, or NaCl) is different from the products (sodium cation and chlorine anion). Sodium is a positive ion . Here's why: A .

Match. Score: 4.9/5 (65 votes) . Why is salt dissolving in water not a chemical change? The solid table salt is added to the water and disappears. sugar in water! Learn. In contrast, dissolving sugar or another covalent compound is a physical change because chemical bonds are not broken and new products are not formed. Sometimes it is difficult to determine whether a change is physical or chemical. If I took an ice cube and melted it, I could reverse the process and turn my water back . Dissolving compounds is decidedly physical. Dissolving sugar in water is an example of a physical change. The reactant (sodium chloride, or NaCl) is different from the products (sodium cation and chlorine anion). Dissolving is a PHYSICAL CHANGE. Dissolving sugar in water is an example of a physical change. In contrast, dissolving a covalent compound like sugar does not result in a chemical reaction. chemical. Dissolving salt in water is a commonly used example of a physical change, but when you dissolve salt (NaCl) in water (H 2 O), you get sodium ions (Na+) and chlorine ions (Cl-) mixed with the water (H 2 O). In a chemical change the molecular composition of a substance completely changes and a new system is formed. . Dissolving a Chemical or Physical Change.
