Understanding Solubility Curves

What does it mean when a solution is saturated?

• It can only dissolve gases.

• It has no solute dissolved.

• It has the maximum amount of solute dissolved.

• It can dissolve more solute.

What is an example of a supersaturated solution?

• A solution with no solute.

• A solution with less solute than it can hold.

• A solution with more solute than it can normally hold at a given temperature.

• A solution with only gases dissolved.

What does a point on the solubility curve represent?

• The amount of solute that can be dissolved at a given temperature.

• The amount of solute that cannot be dissolved.

• The amount of solute that can dissolve in cold water only.

• The temperature at which no solute can dissolve.

What does the area below the solubility curve represent?

• Unsaturated solutions

• Supersaturated solutions

• Saturated solutions

• No solutions

How does the solubility of sugar change with temperature?

• It increases as temperature increases.

• It decreases only in cold water.

• It remains constant regardless of temperature.

• It decreases as temperature increases.

How does salt's solubility in water change with temperature?

• It significantly increases with temperature.

• It remains almost the same regardless of temperature.

• It decreases with temperature.

• It only dissolves in cold water.
