Understanding Solubility Curves

What does the y-axis represent on a solubility curve?

• Density of the solution

• Volume of water in milliliters

• Temperature in degrees Celsius

• Grams of solute per 100 grams of water

How many grams of potassium nitrate can dissolve in 100 grams of water at 50 degrees Celsius?

• 90 grams

• 80 grams

• 70 grams

• 60 grams

If a solution contains 60 grams of ammonium chloride in 100 grams of water at 90 degrees Celsius, what type of solution is it?

• Saturated

• Dilute

• Unsaturated

• Supersaturated

What would be the state of a solution with 95 grams of ammonium chloride in 100 grams of water at 90 degrees Celsius?

• Unsaturated

• Saturated

• Concentrated

• Supersaturated

• 5 grams

• 10 grams

• 15 grams
