Question 17 • AP Biology - SC5182 A

When adding more sucrose to a 0.7M sucrose solution, why does it not dissolve as readily as it did at a lower molarity?

Answer
A
The ions in the solution interact with the sugar and that interferes with its solubility.
B
The solubility of the solute depends on whether the solute has hydroxyl functional groups or not.
C
The solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules.
D
Hydrogen bonds in the water molecules change the electrical charge of the sugar molecule, which prevents it from dissolving further in the water.
