explain the solution types in each glass of lemonade with a complete sentence for each glass. be sure to use terms such as solution, solute, unsaturated, saturated and super saturated.

Explanation:

• First Glass: The lemonade in the first glass is an unsaturated solution because the added solute (sugar) dissolves completely, meaning more solute can still be dissolved in the solvent (lemonade).
• Second Glass: The lemonade in the second glass is a saturated solution as the solute (sugar) is dissolving but at the point where the solvent can hold no more solute at that temperature (no undissolved sugar yet, but it's at the saturation point).
• Third Glass: The lemonade in the third glass is a supersaturated solution because there is undissolved solute (sugar) at the bottom, indicating that more solute was dissolved than the solvent can normally hold at that temperature, and the excess has crystallized out.

Answer:

• First Glass: The lemonade in the first glass is an unsaturated solution as the added sugar (solute) dissolves completely, showing the solvent can still accept more solute.
• Second Glass: The lemonade in the second glass is a saturated solution since the sugar (solute) is dissolving at the maximum amount the lemonade (solvent) can hold at that temperature (no undissolved sugar remains).
• Third Glass: The lemonade in the third glass is a supersaturated solution because undissolved sugar (solute) is present at the bottom, meaning more solute was dissolved than the solvent could normally retain, and the excess has precipitated.
