SOME EXAMPLES TO TRY
1) What are two way
that we can distinguish colloid particles from particles in true solution?
2) Use the Gouy-Chapman model of the
diffuse double layer to predict why the
addition of 1.0 M BaCl2 to a colloid is
more successful than the addition of a
1.0 M solution of NaCl in causing the
colloid to flocculate.
