Exploring Unsaturated, Saturated, and Supersaturated Solutions

What does solubility indicate in a solution?

• The maximum amount of solute that can dissolve in a solvent under specific conditions

• The amount of solvent needed to dissolve a solute

• The maximum temperature a solution can reach

• The rate at which a solute dissolves in a solvent

What characterizes an unsaturated solution?

• It has solute that remains undissolved at the bottom

• It contains the maximum amount of solute that can dissolve

• It cannot dissolve any more solute regardless of temperature

• It can dissolve more solute at the current temperature

What happens when you add more solute to a saturated solution at the same temperature?

• The extra solute remains undissolved

• The temperature of the solution increases

• The solution becomes unsaturated

• The additional solute dissolves immediately

How can you increase the solubility of a solute in a solution?

• By increasing the temperature

• By cooling down the solution

• By adding more solvent

• By decreasing the amount of solute

What is a supersaturated solution?

• A solution that contains less solute than it can potentially dissolve

• A solution that has all its solute crystallized

• A solution that has dissolved solute beyond its theoretical solubility limit at a given temperature

• A solution that cannot dissolve any more solute at any temperature

What triggers recrystallization in a supersaturated solution?

• Adding more solvent

• Stirring the solution vigorously

• Lowering the solution's temperature rapidly

• Introducing a seed crystal

What is the role of temperature in creating a supersaturated solution?

• Raising then slowly lowering the temperature can create a supersaturated solution

• Constant temperature is needed to maintain supersaturation

• Lowering the temperature increases solubility

• Temperature has no effect on solubility

What happens to a supersaturated solution when a seed crystal is added?

• The solution turns into a solid

• The solution becomes unsaturated

• The solute immediately crystallizes

• The temperature of the solution increases

Why are supersaturated solutions considered unstable?

• They turn into solids over time

• They change temperature spontaneously

• They cannot dissolve any solute

• They can easily crystallize upon disturbance

How is rock candy made?

• By freezing a saturated solution of sugar

• By boiling water and adding sugar until no more can dissolve, then cooling it slowly

• By crystallizing sugar in an unsaturated solution

• By adding sugar to cold water until it no longer dissolves
