Quizplus · Accepted Answer

A colloid is a mixture in which one substance is dispersed evenly throughout another substance. A homogeneous mixture is a solution, in which the particles are not dispersed and are of molecular size, and therefore cannot be classified as a colloid. Emulsions, aerosols, and foams are all examples of colloids.
