Decoding Solubility Curves in Chemistry

What does a solubility curve show?

• The amount of solvent in a solution at different temperatures

• The amount of solute that can dissolve in a solvent at different temperatures

• The boiling point of different solutions

• The freezing point of different solutions

What does it mean if a solution is saturated?

• It is at its boiling point

• It has no solute dissolved

• It has the maximum amount of solute dissolved

• It can dissolve more solute

At 30 degrees Celsius, how many grams of sodium nitrate can fully dissolve in 100 grams of water?

• 97 grams

• 70 grams

• 120 grams

• 50 grams

What characterizes an unsaturated solution?

• It has more solute than can be dissolved

• It has the maximum amount of solute dissolved

• It can dissolve more solute

• It is at its freezing point

If a solution at 50 degrees Celsius contains 97 grams of solute, what type of solution is it?

• Saturated

• Supersaturated

• Diluted

• Unsaturated

What does 'supersaturated' mean in terms of solubility?

• The solution is at its boiling point

• The solution has more solute than can be dissolved

• The solution has the maximum amount of solute dissolved

• The solution can dissolve more solute

At 10 degrees Celsius, how many grams of potassium iodide can dissolve in 100 grams of water?

• 100 grams

• 135 grams

• 120 grams

• 140 grams

What happens to the excess solute in a supersaturated solution?

• It reacts with the solvent

• It precipitates out

• It remains dissolved

• It evaporates

At what temperature will 20 grams of SO2 fully dissolve?

• 0 degrees Celsius

• 5 degrees Celsius

• 10 degrees Celsius

• 15 degrees Celsius
