Review

The strong intermolecular force that forms between water molecules is called?

• Hydrogen Bonding

• London Dispersion Force

• Dipole Bonding

In a solution of salt water, two things are mixed: salt and water. If water does the dissolving, what is it called?

• Solvent

• Solute

• Solution

A ________ solution is a solution where water is the solvent.

• Water

• Aqueous

• Agua

Why does salt dissolve in water?

• Salt is made of nonpolar molecules

• Salt does not dissolve

• Salt gets pulled apart by charge attractions with water

• The fast motion of the water molecules collides with the salt ions, breaking them off if they have enough force

What type of compounds do not dissolve in water?

• Ionic

• Polar

• All Dissolve

• Nonpolar

A polar substance will dissolve...

• Only ionic compounds

• Polar and nonpolar substances

• Other polar and ionic substances

• Only nonpolar substances

Why won't water and oil mix?

• Water is polar and oil is nonpolar

• Because water is nonpolar so it can only dissolve nonpolar substances

• Water and oil have different densities, so they can't dissolve into one another

• They can mix if shaken vigorously

Which will dissolve in water? (Hint: Polar dissolves polar and nonpolar dissolves nonpolar)

• Potassium chloride (KCl) (salt like)

• Iodine (I2)

• Benzene (C6H6)

Which will not dissolve in water? (Hint: Polar dissolves polar and nonpolar dissolves nonpolar)

• NaCl (Ionic)

• HCl (Polar)

• Cl2 (Nonpolar)

Do Ionic or Covalent compounds create an electric current when dissolved?

• Ionic

• Covalent
