When some of the sugar added to iced tea remains undissolved at the bottom of the glass, the solution is polar. unsaturated. saturated. dilute. nonpolar?

            When some of the sugar added to iced tea remains undissolved at the bottom of the glass, the solution is Saturated.

Explanation:
                   Solutions are made up of solute (less quantity) and Solvent (higher quantity). Those solutions which are less concentrated and has the tendency to dissolve more solute are said to be Unsaturated solutions. While, those solutions which at given temperature does not dissolve more solute when added are said to be Saturated solutions. Also, saturated solutions are more concentrated than unsaturated solutions.
