- Lesson 5.4: Why Does Water Dissolve Sugar?
Sucrose 1. The ball-and-stick and first space-filling model show that sucrose is a large molecule made up of carbon, oxygen, and hydrogen. Sucrose has many O–H bonds which are polar. These polar areas are shown with a + near the hydrogen atom and a − near the oxygen atom.
When sugar dissolves in water, water particles pull sugar particles off the sugar crystal. Water particles are not actually water molecules. Concentrated solutions contain a large amount of solute for a certain volume of solvent. Dilute solutions contain a large amount of solute for a certain volume of solvent.
have different solubilities. In middle school, students can weigh the solutes for a solubility test that uses equal masses. 2. Add 10 milliliters (2 teaspoons) of water to two separate cups. 3. At the same time, pour the water into the sugar and salt cups. 4. Gently swirl the cups to see whether sugar or salt dissolves the most. Expected results
