Orange juice with pulp is a heterogeneous mixture. The pulp is not uniformly distributed throughout the juice, often settling at the bottom of the jug, resulting in regions with distinctly different properties.
Definition of Heterogeneous Mixtures. A mixture is a combination of two or more pure substances in which the original substances retain their chemical properties. In some mixtures, the initial substances cannot be detected after they have been mixed. In a heterogeneous mixture, the substances do not blend smoothly throughout, and the individual substances that compose the mixture can be detected. Heterogeneous mixtures can typically be separated back into their individual components through chemical or physical means.
