and a solid sol, give an example

1)colloid eg. oil paint.
dis. Phase solid / dis. Medium liquid
solid sol eg. pigment + nylon polymer = pigmented plastic
dis. Phase solid / dis. Medium solid.
dis. Phase solid / dis. Medium liquid
solid sol eg. pigment + nylon polymer = pigmented plastic
dis. Phase solid / dis. Medium solid.
A solid sol is a disperse system where the
dispersion medium is a solid (here the polymer)
containing the finely dispersed phase which is also a
solid (here the pigment particles) whereas the
colloid
has a liquid (here oil) dispersion medium.
has a liquid (here oil) dispersion medium.
