Is potato salad an homogeneous mixture or heterogeneous mixture?

* Heterogeneous mixtures have components that are visibly distinct and can be separated.

* Homogeneous mixtures have a uniform composition throughout.

Potato salad has:

* Potatoes: Solid chunks

* Mayonnaise: Creamy liquid

* Other ingredients: Onions, celery, hard-boiled eggs, etc.

These ingredients are not evenly distributed throughout the salad. You can easily see the different parts and even separate them out.

Therefore, potato salad is a heterogeneous mixture.
