30 lip 2024 · Knowing what you do about the polarity of water, why do you think water dissolves sugar? Students may think that sugar is made of ionic bonds like salt. Or they might think that sugar has positive and negative areas and this is why water is attracted to it.
Water molecules arrange themselves around the sucrose molecules according to opposite polar areas. The attraction of the water molecules and their motion overcome the attraction between sucrose molecules. The sucrose molecules dissolve as they are separated from each other and mix into the water.
Dissolving Sugar at Different Heats. Learn about solutions as you add more and more sugar cubes to different temperature water. This easy experiment shows that you can only dissolve a certain amount and that this changes as the water gets hotter.
When you mix sugar with water, the sugar dissolves to make a transparent solution. Salt is soluble in water too. The substance that dissolves is called the solute.
