Which unit is commonly used on the y-axis of a solubility curve?

• Grams of solute per liter of solvent

• Grams of solute per 100 ml of H2O

• Grams of solute per 100 grams of H2O

• Grams of solute per cubic meter of solvent

How do you find the solubility of a substance at a given temperature using the solubility curve?

• Locate the temperature on the y-axis and draw a line to the curve

• Locate the temperature on the x-axis and draw a line to the curve

• Locate the solubility on the y-axis and draw a line to the curve

• Locate the solubility on the x-axis and draw a line to the curve

If 60 grams of copper sulfate can be dissolved in 100 ml of water, what is the temperature according to the solubility curve?

• 50 degrees Celsius

• 40 degrees Celsius

• 59 degrees Celsius

• 70 degrees Celsius

What does it mean if a solution is below the solubility curve?

• The solution is saturated

• The solution is unsaturated

• The solution is supersaturated

• The solution is at equilibrium

At 70 degrees Celsius, 40 grams of copper sulfate in 100 ml of water is considered:

• Saturated

• Unsaturated

• Supersaturated

• At equilibrium

What is the solubility of copper sulfate at 70 degrees Celsius?

• 40 grams

• 100 grams

• 60 grams

• 72 grams
