Orange juice can be considered a heterogeneous mixture, particularly when it contains pulp. A heterogeneous mixture is one in which the components can be visually distinguished and are not uniform throughout. In the case of orange juice with pulp, the juice and the pulp particles are not evenly distributed.
However, if the orange juice is completely filtered and free of pulp, it may appear more homogeneous, as the components would be uniformly mixed. In general, whether orange juice is classified as homogeneous or heterogeneous can depend on its preparation and contents.
