Which of the following is a homogeneous mixture? Orange juice with pulpSand and waterAirOrange juice with pulpSave

To determine which of the options is a homogeneous mixture, we should first understand what a homogeneous mixture is. A homogeneous mixture is a combination of two or more substances that are evenly distributed, such that the composition is uniform throughout. Let's analyze each option provided:

1. Orange juice with pulp: This is not homogeneous because the pulp does not dissolve and is visibly separate from the liquid juice.

2. Sand and water: This is also not homogeneous. Sand does not dissolve in water, so you can see distinct particles of sand.

3. Air: This is a homogeneous mixture because its composition is uniform, consisting of gases like nitrogen, oxygen, and other trace gases that are evenly mixed.

4. Orange juice with pulp (repeated option): Again, as mentioned, this is not homogeneous.

Conclusion

Among the provided options, air is the only homogeneous mixture.
