Exploring Solubility Curves and Solution Types

What happens when a solute dissolves in a solvent?

• The solute particles are evenly distributed throughout the solvent.

• The solvent particles dissolve in the solute.

• The solute and solvent form a solid compound.

• The solute particles increase in size.

What does a solubility curve represent?

• The freezing point of the solute at different temperatures.

• The boiling point of the solvent at different pressures.

• The maximum amount of solute that can dissolve in a solvent at various temperatures.

• The color change of the solution upon reaching saturation.

What is a saturated solution?

• A solution that changes color when more solute is added.

• A solution that can dissolve more solute at a given temperature.

• A solution that forms crystals when heated.

• A solution that cannot dissolve more solute at a given temperature.

What is the saturation point of a solute at 70 degrees Celsius?

• 100 grams per 100 ml of solvent

• 90 grams per 100 ml of solvent

• 132 grams per 100 ml of solvent

• 122 grams per 100 ml of solvent

At what temperature does a solute have a saturation point of 160 grams per 100 ml of water?

• 70 degrees Celsius

• 93 degrees Celsius

• 80 degrees Celsius

• 90 degrees Celsius

How can a supersaturated solution be created?

• By freezing the solution and then thawing it.

• By heating a solution, dissolving more solute than it can hold at room temperature, and then carefully cooling it.

• By cooling a saturated solution without adding more solute.

• By adding more solvent to an unsaturated solution.

What happens if you add 140 grams of solute to 100 ml of water at 90 degrees Celsius?

• The solution remains unsaturated.

• The solution becomes supersaturated.

• All of the solute dissolves.

• Not all of the solute dissolves.

What is the role of a site of nucleation in the formation of a supersaturated solution?

• It provides a surface for crystals to form around.

• It acts as a catalyst for the dissolution process.

• It increases the temperature of the solution.

• It prevents the solute from dissolving.

Which substance is more soluble at 80 degrees Celsius?

• Sodium chloride

• Ammonium sulfate

• Potassium nitrate

• Sugar

What are the two substances that have the same saturation point at 59 degrees Celsius?

• Sugar and potassium nitrate

• Ammonium sulfate and potassium nitrate

• Ammonium sulfate and sodium chloride

• Potassium nitrate and sodium chloride
