* Solution: A homogeneous mixture where one substance (the solute, sugar in this case) dissolves completely into another (the solvent, water) to form a single, uniform phase.

* Mixture: A combination of two or more substances where each substance retains its own properties.

Key Features of a Solution:

* Uniform composition: The sugar is evenly distributed throughout the water. You can't see individual sugar particles.

* Single phase: The sugar and water combine to form a single liquid phase.

* Separation difficult: You need to evaporate the water to get the sugar back.
