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.
Heterogeneous mixtures contain particles that retain their chemical properties when they are mixed and can be distinguished after they are mixed. The components of heterogeneous mixtures can be separated by filtration of chemical procedures. The two types of heterogeneous mixtures are suspensions and colloids.
