Solubility 1 Quiz

What does "saturated" mean when referring to a solution in chemistry?

• The solution has less solute than it can hold at a constant temperature.

• The solution has as much solute as it can hold at a constant temperature.

• The solution can continue to dissolve more solute without any limit.

• The solution changes color due to the amount of solute.

What is the maximum amount of sucrose that can dissolve completely in 100 mL of water at 20°C?

• 100 grams

• 150 grams

• 200 grams

• 250 grams

Why is it important to express temperature when discussing solubility?

• Because temperature does not affect solubility.

• Because temperature only affects the color of the solution.

• Because temperature affects the solubility of many substances.

• Because temperature is only relevant for solutions above 100°C.

At what temperature range is much more sucrose required to create a saturated solution compared to temperatures between 0°C and 20°C?

• Between 20°C and 40°C

• Between 40°C and 60°C

• Between 60°C and 100°C

• Above 100°C

According to the graph, how does the solubility of sodium chloride change with temperature?

• It decreases significantly.

• It increases significantly.

• It does not change significantly.

• It fluctuates unpredictably.

What is the key to forming supersaturated solutions?

• Cooling the solution rapidly

• Solubility as a function of temperature

• Adding more solute than the solvent can dissolve

• Stirring the solution continuously

A supersaturated solution contains more dissolved solute than a _______ solution at the same temperature.

• diluted

• unsaturated

• saturated

• concentrated

Supersaturated solutions are unstable because if the solution is disturbed, the excess solute can _______.

• evaporate

• dissolve further

• come out of solution and crystallize

• become a saturated solution
