* Mixture: A mixture is a combination of two or more substances where each substance retains its own chemical identity. Sugar and water don't chemically react to form a new substance.
* Solution: A solution is a special type of mixture where one substance (the solute, like sugar) dissolves completely into another substance (the solvent, like water). The resulting mixture is homogeneous, meaning it has a uniform composition throughout.
In summary: Sugar dissolved in water is a homogeneous mixture, specifically a solution, because the sugar dissolves completely into the water.
