2ND QUARTER SCIE 6 24-25

IDefine colloidal dispersion.

• 
  A true solution with particles suspended in the solvent.

• Small particles suspended in solvent; not a true solution.

• A heterogenous mixture of an immiscible solute and solvent.

In what type of phase might you find colloidal dispersion?

• 
  Solid

• 
  Liquid

• 
  Gas

• 
  Mixture

What is the Tyndall effect?

• 
  The inability of oil to mix with water.

• 
  How the tides effect a solution's ability to mix.

• 
  The scattering of light due to colloids.

Why do colloid particles seem to float in solution?

• They are too small to settle out by gravity.

• They are anti-gravitational particles

• 
  They disperse so that they are equidistant from each other.

Which of the following is the definition of solute?

• 
  A species formed and used up; will not appear in rate law.

• The minor component (is dissolved).

• Small particles suspended in solvent, not true solution.

• 
  A solid catalyst in an aqueous reaction.
