What kind of mixture is Italian dressing?

Here's why:

* Heterogeneous mixtures have components that are not evenly distributed throughout the mixture. You can usually see the different parts of the mixture.

* Italian dressing contains oil, vinegar, herbs, and spices. The oil and vinegar don't mix completely, creating distinct layers. You can also easily see the herbs and spices suspended within the dressing.

Therefore, because its components are not uniformly spread, Italian dressing fits the definition of a heterogeneous mixture.
