What happens at the molecular level when sugar dissolves in water?
A
Sugar molecules remain intact and settle at the bottom.
B
Sugar molecules break down into individual atoms.
C
Sugar molecules disperse evenly throughout the water.
D
Sugar molecules form a new compound with water.
Verified step by step guidance1
Begin by understanding the nature of sugar and water. Sugar is a molecular compound, typically sucrose (C₁₂H₂₂O₁₁), and water is a polar solvent.
When sugar is added to water, the polar water molecules interact with the sugar molecules. The partial positive and negative charges on the water molecules attract the polar regions of the sugar molecules.
This interaction causes the sugar molecules to separate from each other and become surrounded by water molecules, a process known as solvation.
During solvation, the sugar molecules do not break down into individual atoms or form new compounds. Instead, they remain intact as whole molecules.
As the sugar molecules are surrounded by water molecules, they disperse evenly throughout the solution, resulting in a homogeneous mixture where the sugar is dissolved in the water.
