  6. A colloid is a mixture composed of particles in a dispersing medium. A colloid is defined by the size of the particles involved. If the particles in a mixture are on the scale of individual molecules, around 1 nanometer, it is defined as a solution. If the particles are larger than 1,000 nanometers, it is a suspension. Anything in between is a colloid. The unique characteristics of colloids are due to this intermediate size of the dispersed particles.
