Intermolecular Forces and Solutions

What are the four main types of intermolecular forces?

• Metallic bonds

• Hydrogen bonding, dipole-dipole interactions, London dispersion forces, ion-dipole forces.

• Covalent bonds

• Van der Waals forces

How does increasing temperature generally affect the solubility of solids in liquids?

• Solubility of solids in liquids is only affected by pressure, not temperature.

• Increasing temperature generally increases the solubility of solids in liquids.

• Increasing temperature decreases the solubility of solids in liquids.

• Temperature has no effect on the solubility of solids in liquids.

What is the effect of pressure on the solubility of gases in liquids?

• Increasing temperature decreases the solubility of gases in liquids.

• Pressure has no effect on the solubility of gases in liquids.

• Increasing pressure increases the solubility of gases in liquids.

• Decreasing pressure increases the solubility of gases in liquids.

Explain how the nature of solute and solvent affects solubility.

• The color of the solute affects its solubility.

• Solubility is only determined by temperature.

• All solutes are equally soluble in any solvent.

• The solubility of a solute is affected by its polarity and intermolecular forces in relation to the solvent.

Define molarity and provide the formula for calculating it.

• Molarity (M) = moles of solute / milliliters of solution

• Molarity (M) = liters of solution / moles of solute

• Molarity (M) = moles of solute / liters of solution

• Molarity (M) = grams of solute / liters of solution

I am a mixture where the solute is completly dissolved in the solvent, forming a homogenous system. What am I?

What is the relationship between temperature and the solubility of gases?

• The solubility of gases increases with increasing temperature.

• Temperature has no effect on the solubility of gases.

• Gases are more soluble at higher pressures regardless of temperature.

• The solubility of gases decreases with increasing temperature.

How do ionic compounds typically behave in terms of solubility in water?

• Ionic compounds are insoluble in water.

• Ionic compounds are generally soluble in water.

• Ionic compounds only dissolve in organic solvents.

• Ionic compounds are always solid and do not dissolve in any liquid.

Calculate the molarity of a solution containing 5 moles of solute in 2 liters of solution.

• 3.0 M

• 2.5 M

• 0.5 M

• 1.5 M

What factors can influence the rate at which a solute dissolves in a solvent?

• Size of the container

• Color of the solute

• Temperature, agitation, surface area, and pressure.

• Concentration of the solvent
