This raises the question: what exactly is a solution and what does it mean to dissolve? You are probably thinking of examples like sugar or salt dissolved in water or soda. What about milk?
Jun 19, 2020 · When water dissolves sugar, it separates the individual sugar molecules by disrupting the attractive forces, but it does not break the covalent bonds between the carbon, hydrogen, and oxygen atoms. Dissolved sugar molecules are also hydrated.
When you mix sugar with water, the sugar dissolves to make a transparent solution. Salt is soluble in water too. Substances that do not dissolve in water are called insoluble substances.

A chemical change involves a chemical reaction and the formation of new products. Dissolving salt in water may be written as a chemical reaction, where sodium chloride dissociates into Na+ ions and Cl–ions in water. NaCl(s) → Na+(aq) + Cl–(aq) When salt dissolves, the ionic bonds between the atoms break. The reactant (sodium chloride or NaCl) diffe...
A physical change involves a change in a physical property, but not a change in chemical composition. Examples include changes in states of matter or alterations to crystal structure. Dissolving salt in water may be considered a physical change because no change occurs in the electron shells of the sodium and chlorine atoms and no chemical reaction...
On the one hand, discussing whether dissolving sugar and salt are chemical or physical changes is a good way to get students thinking about changes in matter. It’s an opportunity to talk about how you know whether a chemical reaction has occurred. On the other hand, all of the signs of a chemical change (temperature change, color change, odor, bubb...

ISBN: 0-395-98583-8.For example, salt and sugar are both soluble in water. . If it cannot dissolve, it is described as insoluble. Heating, stirring and using fine powders are all ways to speed up dissolving.
May 19, 2021 · Example \(\PageIndex{1}\): Sugar and Water. A solution is made by dissolving 1.00 g of sucrose (\(\ce{C12H22O11}\)) in 100.0 g of liquid water. Identify the solvent and solute in the resulting solution. Solution. Either by mass or by moles, the obvious minor component is sucrose, so it is the solute. Water—the majority component—is the ...

Aug 29, 2022 · Dissolving sugar in water is an example of a physical change. 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. A chemical reaction would have to occur. However, mixing sugar and water simply produces... sugar in water!
