If you add sugar to lemonade but notice that the sugar is sitting un dissolved at the bottom is the lemonade saturated, pure saturated or unsaturated

Saturated

Explanation:

If the sugar sits undissolved at the bottom even after vigorous stirring, the lemonade has dissolved all the sugar it can hold. The lemonade is saturated.

If the lemonade were unsaturated, it could hold more sugar and that at the bottom would continue to dissolve.

The lemonade cannot be supersaturated because, if it were, the solid at the bottom would serve as nuclei on which the excess sugar in the solution could form more crystals.

dynamic equilibrium is the answer.
