Sugar dissolved in water is classified as what type of mixture?

When sugar is dissolved in water, it forms a solution. In a solution, one substance (the solute, which in this case is sugar) is completely dissolved in another substance (the solvent, which is water). This results in a homogeneous mixture where the individual particles of sugar are evenly distributed throughout the water at a molecular level, making it impossible to distinguish between the solute and solvent with the naked eye.

In contrast, a suspension involves larger particles that do not dissolve but remain suspended in the liquid and can settle over time. A colloid consists of intermediate-sized particles that do not settle out and can scatter light but do not create a fully transparent mixture. An emulsion is a mixture of two immiscible liquids (like oil and water) where one liquid contains a dispersion of the other. Thus, the unique characteristics of a solution, with its uniform and stable composition, clearly identify the mixture of sugar and water as a solution.
