12L1 Solubility and Concentration

How can you determine the amount of solute that can dissolve in a given amount of solvent at a specific temperature?

• Observing the color change

• Calculating the molecular weight

• Using solubility curves

• By measuring the pH

What does it mean when a solution is saturated?

• It cannot dissolve more solute at a given temperature

• It can dissolve more solute

• It has a low concentration of solute

• It is at room temperature

Which term describes a solution that contains more dissolved solute than is present in a saturated solution at the same temperature?

• Dilute

• Concentrated

• Unsaturated

• Supersaturated

What is the difference between a dilute and a concentrated solution?

• The color of the solution

• The amount of solute

• The temperature of the solution

• The amount of solvent

Which factor does NOT affect the solubility of a substance?

• Temperature

• Pressure

• Color

• Nature of solute and solvent

How does increasing the temperature generally affect the solubility of a solid in a liquid?

• Decreases solubility

• Increases solubility

• No effect on solubility

• First increases then decreases

What is the effect of surface area on the solubility of a solute?

• Increasing surface area decreases solubility

• Increasing surface area has no effect on solubility

• Increasing surface area increases solubility

• Initially increases solubility, then decreases

A homogeneous mixture is also known as a ______.

• Solution

• Element

• Compound

What conclusion can be made using this solubility curve?

• Decreasing temperatures always increases solubility 

• Increasing temperatures always increases solubility

• Increasing temperatures usually increases solubility

• Temperature has no affect on solubility

Based on the solubility curve, what is the maximum number of grams of KCI_(s) that will dissolve in 100 grams of water at 50°C to produce a saturated solution?

• 38g

• 42g

• 58g

• 84g
