Unit 4 Lesson 3: Intermolecular Forces in Mixtures

Which of the following substances would conduct electricity if dissolved in water to form a solution?

• C₆H₁₂O₆

• CH₄

• KI

• CO₂

A conductivity probe is placed in a solution of water and an unknown solute. The bulb doesn't light up. What can you determine about the unknown solute?

• It is an ionic compound.

• It is a metallic compound.

• It is a molecular compound.

• Not enough information is given to answer this question.

What happens to the concentration and conductivity, when you increase the amount of solute in a solution?

• The concentration increases and conductivity increases.

• The concentration increases and the conductivity decreases.

• The concentration decreases and the conductivity decreases.

• The concentration decreases and the conductivity increases.

Sugar dissolves in water through

• ionization

• dissociation

• neutralization

• dispersion

Ionic compounds produce ions in solution by

• Ionization

• dissociation

• evaporation

• dispersion

What does it mean to be "Soluble" ?

• Capable of being a solid.
• To have soul.
• Capable of being dissolved.
• To sink.

Which of the following are considered to be a homogeneous mixture?

• Colloid
• Solution
• Suspension
• All Mixtures

What is the unit for molarity?

• mass/liters
• moles
• liters
• moles/liter

A measure of the amount of solute in a given amount of solvent or solution is...

• saturated
• solubility
• concentration
• miscible

A saturated solution is one that....

• contains the maximum amount of dissolved solute.
• contains less solute than a saturated solution.
• contains more solute than a saturated solution.
• is the amount of a substance required to form a saturated solution.
